Other mistake: Louella Parsons walks out of a screening of Citizen Kane before it ends, but later tells Hearst that Rosebud was Kane's sled. She shouldn't know that, because the identity of Rosebud is only revealed in the final scene of the movie.

Other mistake: The chain "securing" the lock on the boarded up "Metro Christian Shelter" is in some inexplicable way on both sides of a 4" board that is taut between two other parallel boards. However, when the men are using the bolt cutter, the right side of the chain extends from a hole in the middle board, and the left side goes around the side of that same board and then around a pipe that is not originally there. The board that is to the left is missing. (00:17:17)
