Revealing mistake: When the Lion is pulling up the Tin Man with his tail on the way to the castle, you can see a square block inside the Lion's costume to hold the tail on.
Continuity mistake: When Scarecrow, Tin Man, and the Cowardly Lion are marching into the Wicked Witch's castle after taking the guards' uniforms, all three of them are shown holding the same types of spears as the guards, so when they go rescue Dorothy out of the locked room and Tin Man chops through the door with his axe, where did the axe come from?
Continuity mistake: As the chandelier falls on the guards at the witch's castle, all the candles are blown out by the time it lands. The next shot shows some of them relit.
Continuity mistake: Immediately after Dorothy throws the water onto the witch, there is a long shot of the group as they observe the Wicked Witch beginning to melt. In this shot you can see that the Scarecrow's arm is still on fire, yet nothing is done about it as they all focus on the Witch. In the next full shot of the Scarecrow the fire is completely out.
Revealing mistake: When everyone is still in the poppy field, after the snowstorm, Dorothy says "Look. Emerald City is closer and prettier than ever." Look behind the Lion just as Dorothy says the word "City" and you'll see that the wire attached to his tail brushes over the top of some of the poppies, knocking the snow off.
Character mistake: While singing the "If I Were King" song, the Lion asks, "What makes the Sphinx the Seventh Wonder?" The Sphinx is not one of the Seven Wonders of the World; its neighbour the Great Pyramid of Giza is. Besides, how would the residents of Oz know about our Seven Wonders of the World?
Continuity mistake: When the Tin Man, Scarecrow, Cowardly Lion and Dorothy are cornered in the witch's castle, the scarecrow grabs the Tin Man's axe and chops a rope, releasing the chandelier, which falls on the guards. In the next shot, however, as the witch is shrieking "seize them", the guards give chase with only 1 or 2 laying on the floor.
Continuity mistake: When Dorothy is at the end of the movie confronting the Wizard about going home, since she killed the Witch, Toto goes over to the curtain and you can see him tied up to it as he opens it. Dorothy then goes over there and automatically has him in her arms - she didn't even need to bend down and pick Toto up.
Continuity mistake: The blue shirted Lollipop Guilder comes from around the fallen house at the beginning of "Come Out Come Out," but he immediately appears emerging from a jet black manhole (with a black lip where the cover goes) in middle of the yellow brick in front of the house.
Audio problem: At the very end of, "We Welcome You to Munchkin Land," at the very last 'fa la la la la laaaaaa' right before the Wicked Witch interrupts the song with her explosive arrival, you can hear someone scream before the explosion even occurs.
Other mistake: When entering the Haunted Forest, the Scarecrow is carrying a pistol and a stick, the Lion has a bug sprayer and net, the Tin Man has a monkey wrench and his axe. But different scenes after that shows some items missing and then returning. I guess in the insect scene that was cut, they lost all those things but the axe.
Revealing mistake: When the group is waiting to see the Wizard, the Lion sings the "If I Were King" song. The Tin Man grabs a flower pot and breaks it to make a crown. When the crown falls off the Lion's head later, it bounces around like plastic.
Revealing mistake: In the scene when the Wicked Witch of the West bends down to retrieve the ruby shoes from the feet of her sister sticking out underneath Dorothy's house, there is one quick shot in the middle of the scene that shows her in front of a screen with a picture (film) of the house on it. Maybe that shot was filmed after the original set was unavailable? That would seem to be the only possible and reasonable explanation why such a shot would be necessary.
Revealing mistake: If you listen closely, during the singing of "We're Off To See The Wizard" by Dorothy, the Scarecrow and the Tin Man, you can recognise Buddy Ebsen's gravelly voice. He was the original Tin Man, but had a reaction to the makeup. They had already recorded the songs and it was too expensive to re-do it. (This film was WAY over budget and they couldn't waste time and money re-recording songs)
Revealing mistake: When the Wicked Witch scares the Munchkins in Munchkinland, where Dorothy lands, she disappears into a cloud of smoke she creates. But you can see her sneak down into a trap door below. [As a sidenote to this entry, Margaret Hamilton was hospitalized for severe burns after a take of this shot (not the final one used) when there was a glitch in the timing of the explosion.]
Continuity mistake: When Dorothy first meets the scarecrow, there is a patch of grass in front of the field the scarecrow is in. On the grass there's two beds of flowers. The flowers change colors from when Dorothy meets the Scarecrow, to when the Scarecrow starts his "If only I had a Brain" song.
Revealing mistake: When the Tin Man breaks the flower pot for the Lion in the palace you can see the lines that it is supposed to break on.
Continuity mistake: When the Wicked Witch scares the Scarecrow, Dorothy, and the Tin Man with fire, after the fire is thrown, not only is the Tin Man's funnel cap on backwards, everything is reversed. In order to keep the characters oriented from left to right correctly, they had to show the film from the wrong side, thus the buttons of the Scarecrow's jacket and everything else are on the wrong side.
Continuity mistake: In the scene where the Wicked Witch in Munchkinland goes over to observe the ruby slippers on her dead sister's feet, when she is up close there's not much space between her and the slippers but when she turns around and says "they're gone," she's further away, then she's closer again in the next shot.
Continuity mistake: When the Lion is singing about being King of the Forest, the TinMan breaks a flower pot to "crown" him. Pay close attention, as the break marks on the pot change. In one shot there's a big jagged edge sticking up (obviously longer than the others) and in the next scene most of the edges are even.
Continuity mistake: After the Witch throws a fireball at the Scarecrow in the woods and disappears, Dorothy is holding Toto. But when it cuts to a closeup of her, it looks like her shoulders are extended. When it cuts back to the wide shot, she indeed has her arms around the Scarecrow and Tin Man, even though she never put Toto down.
Revealing mistake: Soon after Dorothy, the Tin Man and the Scarecrow meet the Lion for the first time, they dance along the Yellow Brick Road, singing. As they disappear at the back of the set, their shadows can be seen on the backdrop, equally covering the trees and everything in between. DVD showing.
Other mistake: When the Wicked Witch is giving the orders to the Nikko, the Head Winged Monkey, it shows his troops flying away before he's even finished receiving his orders.
Continuity mistake: The characters change places from one shot to another as the Wizard gives the Tin Man his heart, etc.
Continuity mistake: In the scene where the Tin Man breaks the flower pot for Lion's crown, the top of the flower pot falls away, forming the spikes on the crown. In the next shot when the Lion is wearing the crown, the base has been cut out to allow room for his head.
Continuity mistake: In one of the most endearing scenes from one of the greatest movies of all times, nobody noticed that as Dorothy sings "Over the Rainbow" the haystack she's standing next to just materializes between shots. Later it disappears long before the twister reaches the house. If you watch the movie you'll see the exact spot where the haystack should be seen as Aunt Em gives Dorothy a cruller and says to her, " and find yourself a place where you won't get into any trouble".
Other mistake: As they walk through the forest in the shot before Dorothy says, "I don't like this forest" there are some cool digital glitches in the lower left hand corner of the screen which look like a strand of blue Christmas lights blinking on and off. (Restored and re-mastered DVD version only).
Revealing mistake: In the scene where Dorothy, Tin man, Lion and Scarecrow are in the haunted forest and are discussing whether or not to believe in spooks, Tin Man is lifted up into the air and then comes crashing to the ground. You can see his pants wrinkle up as he's trying to get up. Since when does tin wrinkle like that?
Continuity mistake: Dorothy's Aunt hands out some food, walks with her and leaves Dorothy alone. Several meters ahead there's a cart wheel and one chicken. When the angle changes, Dorothy is standing next to the wheel, which is also facing a different position, and there's a lot of chickens around.
Continuity mistake: In the beginning of the movie Dorothy comes running into the farm and there's an old tire hanging from a tree. Two shots later as she walks away from Aunt Em and Uncle Henry the tire has been moved. The angle at which it hangs has been changed and the piece of rope hanging on the bottom of it is now three or four inches closer to dead center than it was before.
Continuity mistake: As Toto escapes from the Wicked Witch there's a mortar and pestle to the left of the hourglass. In a close-up Dorothy looks at the hourglass after the Wicked Witch turns it over and we see the pestle has been moved to the other side of the mortar. There will be no confusion about this if you look at the direction of the shadow cast by the hour glass.
Revealing mistake: After the witch says "Hey scarecrow, wanna play ball" she throws a fireball at him. But you can see the ground catch on fire before the fireball hits the ground.
Audio problem: After the witch says "Well my little pretty, I can cause accidents too." her mouth starts to move again but nothing is heard.
Continuity mistake: In the farm, after Hunk the farmhand has had his finger smashed, he scolds Dorothy. When she starts to leave, he hammers his hand and takes off his glove, shouting and turning around in pain. The angle swaps to a wide angle and he is working totally calmly with both gloves on.
Continuity mistake: When the four are at the end of the hallway to see the Wizard, Toto is near the lion's feet. As it switches shots, he is behind The Tin Man.
Continuity mistake: When Dorothy walks on the pig sty Zeke walks to his right, looks into, than passes the bucket on the right because it's empty. He then picks up the bucket behind it on the bench and proceeds to feed the pigs. He empties the first bucket then picks up the second empty bucket, which is now three quarters full.
Revealing mistake: As the Tin Man busts down the Witch's door with his ax if you look closely you'll see a slight edit in the film right before he takes his last swing. What they did was unlock the door before the last swing so it would open. You can see the dead bolt retracted as the door swings open.
Continuity mistake: When the Lion, the Scarecrow, and the Tin Man are chopping down the witch's door to free Dorothy before the hourglass runs out, they are dressed in the guards' uniforms. We see the axe hit the door, and in the next wide shot they are not in the uniforms. There is a slight view of the uniforms in a pile on the floor, as if the trio had changed out of them between axe blows.
Continuity mistake: In the scene where the Scarecrow comes down off the pole and onto the yellow brick road, some of his stuffing falls out. You can then see Dorothy pick it up and put it back in. After Dorothy agrees to take the Scarecrow with her and they begin to skip away, you can see the straw that Dorothy supposedly picked up and put back inside the Scarecrow on the road again.
Other mistake: When the munchkin soldiers first arrive, you can see that some of the munchkins in the front are not beating their chest at the same time. This also happens when the munchkins sing the "fa la la la la" song before the witch arrives.
Revealing mistake: In the scene where the Lion sings his "If I Were King" song just before visiting the Wizard, if you watch closely above his moving tail, there is a string holding up and moving around the Lion's tail.
Continuity mistake: During the tornado scene while she's in her bedroom, there is a small oval picture (which looks like Elvira Gulch) over the bed which ends up sideways. As she gets up to leave after the house lands, it's straight up.
Continuity mistake: Just before the group starts skipping towards the Emerald city, there is snow everywhere, but in the next shot, it's completely disappeared.
Continuity mistake: In Munchkinland, when Dorothy walks the road and everyone sings "Follow the yellow brick, follow the yellow brick road," the angle cuts and a group of Munchkins have suddenly appeared in the center of the previously empty road. Dorothy was standing on the farthest point, so they had half a second to walk 10 meters, which is impossible.
Visible crew/equipment: The four run away from the guards and leave the tower where the Wicked Witch is eventually melted. If you look closely in the two long shots from above them, the Tin Man reflects the bright stage light that is placed below them at the first bend of the walkway, on top of the Witch's castle.
Continuity mistake: When everyone is dancing because the witch is dead, joyous soldiers are marching in a straight line, just before the three dancers who represent the lullaby league sing. In one wide shot there are many Munchkins dancing over to form a crowd to the right of the soldiers, but in the next shot all the Munchkins are already standing in one big perfectly formed crowd.
Continuity mistake: In the scene when they discover the Wizard behind the curtain there is a change in the equipment on his wall. At first the big lit up gauge thing with the two levers above it is lit, about a minute later when the Scarecrow gets his diploma the angle has changed and the gauge thing is dark.
Continuity mistake: When Toto pulls the curtain back to show who the real "Oz" truly is it looks like Toto's collar got snagged or he actually had to bite it but in the next shot he pulls the curtain back so fast that it would've sent Toto flying but then he is connected back to it again.
Visible crew/equipment: As Dorothy is leaving Munchkinland the shadow of the camera on its dolly can be seen on the floor to the right of the screen as several Munchkins almost get run over. The shadow of the cameraman's head can be seen on the bottom right of the screen as they pass her house.
Continuity mistake: After the talking trees throw their apples at Dorothy she walks up a small hill and finds the Tin Man. If you look behind her there's a house across the Yellow Brick Road. We just saw this exact same spot in the previous shot as they were being pelted with the apples and the house is not there.
Continuity mistake: When the witch leans over to claim the slippers, she goes really close to them and her broom is practically touching them. Not to mention she also casts a significant shadow on the wall of the house. In the close-up of the slippers disappearing, however, the witch's broom and her shadow are not in the shot although they should be.
Plot hole: In the scene where the Wicked Witch is furious because Dorothy and pals have been saved from the poppy field, the Flying Monkey hands her a golden cap. She then dashes the cap across the room. The golden cap is used in the book to summon the Flying Monkeys. They shot scenes involving use of the cap, edited them out, but left this one with the cap inexplicably being tossed about.
Continuity mistake: We see a Munchkin in a blue shirt climbing out of a manhole in the middle of the Yellow Brick Road and he has a prominent red scarf on. The wardrobe Continuity Person goofs because whenever we see him again, as in a glimpse in the very next shot and when Dorothy leaves Munchkin Land, the red scarf is gone.
Continuity mistake: When the Wicked Witch tells Nikko "throw that basket in the river and drown him" the knife in front of the basket to the right of the hour glass is pointing right in the direction of the round chain hook embedded in the concrete underneath. The next time we see this knife it has moved 90 degrees in relation to the chain hook, without anyone touching it.
Revealing mistake: After the Wicked Witch exits Munchkinland in a puff of red smoke and flames, you can briefly see sulphur marks left on the trapdoor.
Continuity mistake: When Dorothy comes running into the farm at the beginning of the movie, there's a lone cow in the pen behind her and a couple of white chickens that she ends up chasing in the direction of the camera as she runs near the house. Two shots later the cow disappears and the white chickens are now in the pen.
Continuity mistake: When Dorothy is walking toward the Wizard behind the curtain, you can see the flowers in her basket that the munchkins gave her in munchkin land. Later, when the Wizard turns to walk away from the curtained area, suddenly the flowers are set on top of the Wizard's machine. There is no explanation, and you can't see anyone placing them there.
Continuity mistake: Prior to the Tin Man's dance after he's saved by Dorothy and the Scarecrow, there is a shot of Dorothy with the Scarecrow and the Scarecrow is holding the oil can. The camera turns to the dancing Tin Man and when it turns back to Dorothy and the Scarecrow, the oil can has somehow ended up in Dorothy's hand basket.
Continuity mistake: When the companions are walking down the corridor to the wizard's room, Toto is on their left side. Then, the camera view suddenly cuts to being behind them, and in which case, Toto is suddenly on their right side.
Deliberate mistake: Before Dorothy is sent to Kansas there's a close-up of her shoes. All of the group's feet, Glinda's dress, and the rest of the elements around are gone and replaced by a black background. Despite being a deliberate directorial decision to give the shoes a more dramatic focus, it is really awkward to see everything disappear, nevertheless.
Continuity mistake: The Munchkin Mayor's watch keeps changing time, from nearly to the hour, to twenty after the hour.
Continuity mistake: In the scene where the tornado is forcing everyone into the storm cellar, there is a bench lying on its side. In the next scene, when Dorothy arrives at the cellar, the bench is not only turned in an entirely different position and seems to have gotten bigger, but a wash tub has been placed in front of it.
Continuity mistake: Prior to the Wicked Witch attempting to retrieve the ruby slippers from her sister, Dorothy is seen standing in front of Glinda still holding the lollipop she was given. The camera then turns to the Wicked Witch of the West and when it turns back to Dorothy, the lollipop has disappeared.
Continuity mistake: Just after Dorothy takes the cruller and before singing "Over the Rainbow", as she walks along the side of the building and Aunt Em says the words, "Help us out today," notice the wagon wheel leaning against the corner of the structure. Also notice that the fence just beyond the wheel has a broken top rail. Two shots later, a paddle appears and is now leaning against the wheel, and the fence is repaired.
Continuity mistake: As Dorothy balances on the pigsty Zeke feeds the pigs. The bucket he passes by on his right is smooth without any ridges on its sides and the bucket he picks up from the bench has a visible indentation about one inch below the rim. He empties the first bucket than picks up the second, which shouldn't have an indentation around it but does.
Continuity mistake: When the Tin Man is levitated and falls to the ground the metal covering his left leg is crumpled up. When we see him again from behind as the flying monkeys attack, the metal covering his leg has never been bent. The metal on his lower back has also been repaired since the fall.
Continuity mistake: When the Tin Man crowns the Lion with the broken flower pot, he places the crown over the right ear, but in the next shot the crown is over the left ear.
Continuity mistake: When the group emerges from the woods and is looking at the Emerald City, from the front Toto is about ten or fifteen feet to the left, standing on a rock. It then cuts to Dorothy for just a second, and then to a shot of the group from the back, and Toto is suddenly right behind them.
Other mistake: As the Wizard is pulling his curtain closed, he says the famous, "Pay no attention to that man behind the curtain," in a loud, booming voice. But he's turned 180 degrees away from his microphone, which we see a second later needs to be right in front of his mouth to make the booming voice effect.
Continuity mistake: The Wicked Witch of the West's bilious green face colouring changes shades during the film. DVD showing.
Revealing mistake: When the doorman initially refuses to let Dorothy and friends into the Emerald City, they protest, saying the Good Witch of the North sent her; they show him the ruby slippers as proof. As the camera pans down to the slippers, look at the yellow brick road Dorothy is standing on - it is flat and looks as though it was simply painted.
Continuity mistake: During the Tin Man dance, Toto switches from one side of the Tin Man to the other side without walking there.
Continuity mistake: There are two actresses playing Dorothy (and two dogs playing Toto) as she opens the door to Oz. The first is a stand-in wearing a dull colored dress in order to make it look black and white. After she opens the door and moves out of the way, Judy Garland is who we actually see walking through. Look at the different pleats on the two dresses.
Revealing mistake: Throughout the movie, you can tell that if the main characters walking into the distance, the "faraway" landscape is a giant matte painting.
Continuity mistake: During most of the movie, all the characters have at least three shadows, and when the guy that guards the entrance to the Wizard first goes in to speak with him, he has at least 4 or 5.
Revealing mistake: When they first meet the Cowardly Lion, he jumps off of a boulder and obviously lands on a trampoline and jumps off.
Revealing mistake: In the scene where the tornado is about to hit and Aunt Em and Uncle Henry are going into the cellar, you can see that some of the trees are blowing around violently, and others aren't moving at all.
Other mistake: The Witch's castle is shown twice, the first time is in the beginning of the scene when Dorothy is held in her room, and the second time is when Toto brings the three back to rescue her. Each time the painting is almost exact, even down to the lights in the windows of the castle. The only thing that changes is the walk way up to the castle, which is entirely different each time.
