Diary of a MadmanGoofs
When Odette goes to lock her apartment door after her husband storms out, the camera moves in on the doorknob and key, then Simon pushes the door open. No corresponding plate or bolt for the lock and key is visible on the door edge, revealing there is no lock at all. This is a common shortcut used by set carpenters.
At the start of the movie the date in Magistrate Simon Cordier's diary states 1886 as the year. 18-19 minutes into the movie, when he returns the picture of his dead wife and son back to the trunk upstairs, the camera pans to the right after it's open and there is a Teddy Bear. Teddy Bears weren't around until shortly after the November 16, 1902 newspaper cartoon of "Teddy" Roosevelt's based on his bear hunting trip in Mississippi earlier in the month. ("Teddy" refused to kill a baby bear after its mother was killed). Steiff bears started at the Leipzig Toy Fair in March 1903.
