Home Alone (1990) - 44 mistakes

Other: The Murphy's basement is shown to be dripping water from when Marv flooded the kitchen earlier but when the crooks are hit by the old man at the end of the film, the floor is dry even though the faucets are still running.

Continuity: When Joe Pesci places his hand on the red hot doorknob on the front door of Kevin's house, he places his hand on the doorknob sideways, but after he sticks his hand in the snow, he looks at his hand and the letter M that was burned into his hand is straight up and down, not sideways like it should be based on how he grabbed the doorknob.

Revealing: The morning the McCallister's are rushing to get to the airport, the kid from across the street is bothering one of the van drivers. In the scene where the van driver says, "Gee, kid I dunno, hit the road," you can clearly see the kid mouthing the words as the man speaks.

Continuity: Kevin goes out to cut the top off a tree to use as a Christmas tree. The tree top he drags in is much smaller than the one he decorates.

Continuity: When Kevin is leaving the church after talking to the old man that lives next door to him, he runs home. Between leaving the church and getting home he is wearing one pair of trousers, when he gets home he is wearing a pair of jeans, then when he is setting up the traps for the bad guys he is back to other pair of trousers.

Continuity: When Kevin says, "I made my family disappear" and runs around the house, he runs to the foyer and spins in a circle. The window near the stairs is dark meaning it's dark outside. He run upstairs and the window in Kevin's parent's room is also dark. The lights are on too. He then goes to Buzz's room and the kitchen and it's light outside. No lights are on.

Visible crew/equipment: In the scene where Kevin rides the rig on the rope to get to the treehouse, you can see that it was a stuntguy, because Kevin is much smaller.

Continuity: In the scene where Kevin prepares to ride his toboggan down the stairs, the front door changes position between half open and completely open.

Continuity: When the McAllisters leave Chicago, they are flying on a DC-10. The plane that arrives in Paris at the end of the flight is a 757.

Continuity: When Marv comes to the back door while Kevin is washing dishes, Kevin turns on the Johnny & Snakes movie. Then he goes to get the pot and puts the pot by the back door. The whole time he has his sleeves rolled up, but when he opens a drawer to get firecrackers, his sleeves are rolled down. In the very next shot they're rolled up again. The shot changes too quickly for him to roll them back up.

Continuity: In the scene where Kevin is hanging up ornaments on the Christmas tree and he sees Harry peeping through the window by the reflection of the ornament, the reflection is not entirely accurate. It shows Kevin facing the camera with both the tree and window behind him. The reflection should have shown Kevin with just the window behind him and slightly to his right, based on his original position.

Continuity: In the scene where Kevin is putting washing in and taking clothes out of the drier, he places the orange bottle of liquid on top of the washer with the handle facing away. On taking the clothes out of the drier and closing the door, he turns to see the metal heater scaring him by saying "Kevin.". Look over his left shoulder when the shot comes back to Kevin, the orange bottle now has it's handle facing outwards, and the top isn't on properly.

Factual error: When Kevin's mom leaves Paris to return home, the plane shown departing the airport is a DC-9. No airline uses this plane for trans-Atlantic service - it doesn't have the required range.

Other: Toward the end of the film, there is a scene where Macauley Culkin rides a rig on a rope from his house to the treehouse. Joe Pesci and Daniel Stern try to follow, but Culkin cuts the rope with a hedge cutter. Problem is: The rope is slack when Mac cuts it. With the weight of two grown men, it would have been stressed like a guitar string.

Continuity: When Kevin is searching in Buzz' chest, some objects appear or change place after he throws the Playboy magazine away.

Revealing: When Kevin screams from putting on aftershave, the shot cuts to the spider running behind the toilet. You can see white tiny pellets being thrown at the spider from behind. This must have been to make sure it kept moving during the shot.

Continuity: When the first shot of the rigged rope is shown outside of the upstairs window, the rope appears to be horizontal. Yet, when Kevin rides down it, the rope appears to now be sloping downward towards the treehouse.

Continuity: In the shot where Buzz is eating the slice of pizza, he is shoving it into his mouth all bent up. In the next shot from another angle, he is eating it flat and it seems to be a whole new slice.

Continuity: Assuming the McCallisters left Chicago mid-morning as the story suggests (say, between 9 and 10am), and allowing for an 8 hour flight and 7 hour time difference, the flight should be arriving in Paris somewhere between midnight and 1am. However, the footage of the plane landing suggests it is around twilight.

Revealing: When Kevin is washing dishes, there's Bubbles on his hands, but in the next shot there's no bubbles on his hands.
