Being John Malkovich mistakes
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.
