Being John Malkovich (1999) - 7 major mistakes

Continuity: When Craig first discovers the portal door his crouching position changes slightly between the camera shot inside the tunnel and that from the office, and again when he closes the office door and goes back to the portal door.

Continuity: Towards the end after Malkovich gets off the phone with Lester, who threatens him, he has hair over his eyes. In the shot through his eyes however there is no hair seen. When it shows his face again there is still hair.

Continuity: When Craig and Maxine are speaking with their first client (the "Fatman"), Maxine has a clipboard with paper on top on the desk in front of her. When the shot changes, the blue clipboard is now at the top, neither Maxine nor Craig removed the paper.

Continuity: When Malkovich is in the bar at the end he puts his glass on his lap.In the next shot it's on the counter.Then in the next shot it's switched from his left hand to his right.

Continuity: Before, during and shortly after his dance JM has a very visible lipstick mark on his cheek. At the end of the scene the mark disappears, then comes back, and then goes again.

Continuity: Before JM goes through his own portal, he puts on his baseball cap with the strap in the back open. Next he is seen crawling and the strap is closed.

Revealing: At the end when Charlie Sheen is balding you see the edge of the silicone wig in the middle of his forehead.
