Back to the Future

Continuity mistake: When Biff chases Marty out of the cafe in 1955 and Marty 'makes' the skateboard, there is an odd shot of a tree. When Biff's car drives through the grass, the big tree in the shot is shaking violently, yet all the trees are completely still during the chase before and after this shot. During this entire scene, differences regarding varying degrees of windy then calm, wet vs dry pavement and variations in shadows cast are numerous. (01:06:30)

Continuity mistake: In the 1955 skateboard chase scene around the town square, note how the skateboard used throughout the whole chase scene changes at least 4 times. Namely different wheels, trucks and the trucks' wooden mountings. (01:03:15)

Paul Andrews

Revealing mistake: When Marty crosses the park in front of the court house and the camera pans around following Marty while showing the town, watch one of the buildings in the middle background. Part of the building is grey and has 2 windows and is supposed to have a slanted roof, but if you watch closely, it appears that building is in fact only a wall with nothing behind it. (00:34:40)

Continuity mistake: In the chase scene with Marty and the Libyans, Marty is driving away from them. He changes into second gear but in the next shot he shifts into second gear again without changing back. (00:30:15 - 00:31:10)

Continuity mistake: When Marty arrives in 1955, he puts the DeLorean behind the sign, and walks into Hill Valley. When Marty and the 1955 Doc come back later, the DeLorean is facing the other way round to what it was at the beginning (you can tell because at the start Marty pushes the BACK of the DeLorean AWAY from the Lyon's Estates billboard, but when they come later, the FRONT is facing TOWARDS the billboard). (00:35:05 - 00:51:15)

Upvote valid corrections to help move entries into the corrections section.

Suggested correction: I watched the film and the DeLorean does not change direction when behind the billboard; it faces the same direction both when Marty pushes it behind the billboard and when he and the 1955 Doc come back later.

Continuity mistake: When Marty's been thrown back by the amp, the papers on top of him change between the first and second shot. Precisely a Polaroid photo, a poster/map and a vase are missing. (00:04:20)

Factual error: When Marty walks out of Lorraine's house, next to the front door is a light dimmer switch. Dimmer switches weren't invented until the late 1950s to early 1960s. (00:47:34)

Continuity mistake: After George lays Biff out, Marty pulls the family photo from his pocket. The way he holds it suddenly changes, judging by the position of his index finger as the shots change. (01:23:45)

Continuity mistake: At Twin Pines Mall, when Marty is recording Doc Brown, Marty is raising the video camera to record Doc Brown saying, "No, no, no, this sucker's electrical," but when this piece of film is played back in the Doc's garage in 1955 it appears as if Marty was already recording when the Doc starts speaking. (00:25:15 - 00:50:40)

Continuity mistake: At the beginning of the film, when sending the DeLorean into the future, the wide shot shows the DeLorean heading for Marty and Doc then disappears leaving a trail of fire. Notice the cut as the car park goes from being dry to wet with puddles. (00:20:00)

Paul Andrews

Continuity mistake: When Marty is at the "Start" line waiting for the alarm clock to ring, he moves up his return time and the engine stalls out. Next we see Marty turning an ignition key with several other keys on a chain like the ones used on ceiling fans with the little balls and a plastic fob with the paper insert that reads 555-1138 Out-A-Time on it. After Marty arrives back In 1985 in town square, he pauses and gets out for a moment. While returning the the car he puts the DeLorean in drive and again the car stalls out. Again we see Marty restarting the DeLorean, we see a different set of keys. The key mysteriously changed in the time travel to an after market type with a thin wire ring on it, no key fob and the other keys are missing. (01:38:43 - 01:42:44)

Continuity mistake: When the Doc is trying to pull the cable to connect it the cable is stuck and when he pulls the cable hard the other connection breaks off. Watch when it breaks off you cn see that after Doc pulled it the cable gave him more length and would surely get Doc's arm to the other cable but when they show the Doc a second after he hasn't moved one bit. (01:39:35)

Revealing mistake: At the end, the DeLorean hits the left dustbin and comes to a halt - you can easily see that it's not Christopher Lloyd driving, it's someone with a much bigger build, wearing an awful white wig. Further, he isn't wearing sunglasses until he gets out of the car. (01:45:55)

Continuity mistake: After Doc accidentally unplugs the cable and is sending Marty back, he unplugs the cable 15 seconds later and it shows Doc, and the clock's hand change. A split second later the clock's hand changes again.

Visible crew/equipment: When Marty is riding past the cafe on his skateboard and all the chicks are waving at him, you can see the reflection of the camera lorry and crew behind him. (00:06:25)

Continuity mistake: While being chased by Biff, after Marty knocks down a man and a woman, the man stands up and helps the woman stand up, but a frame later he is rolling on the floor with the woman on top of him.

Audio problem: Lorraine comes to see Marty in Doc's garage in 1955 to ask him if he will go to the dance with her. Just before Lorraine moves to the other side of the car from where she walked in, she begins to say something to Marty. The problem is that her lips don't move when she talks, I guess the right clip ended up on the editing room floor. (01:11:40)

Continuity mistake: George McFly's holding a pen in his right hand, then a cut to a wide shot reveals him not holding a pen as he rests his arm away from his body on the table. Then when the camera cuts back his arm is back in front of him holding the pen. (00:14:10)

Trivia: In the battle of the bands scene, when Marty introduces The Pinheads, Huey Lewis, who provided "The Power of Love" for the film's soundtrack, plays the second judge from the left, and is the one who eventually says, "You're just too darn loud." (00:07:40)

Question: What does the saying "Why don't you make like a tree, and get out of here", mean?

Answer: It's a way of saying "scram" or "get lost." But Biff is so dim, he doesn't realize he's saying it wrong; the expression is "make like a tree and leaf", with the joke being that "leaf" is meant to sound like "leave."
