Corrected entry: In the final shoot-out, Officer White advises Detective Exley that he is going under the building by pointing to a square open hole in the floor. The first shot of the hole shows it is clear with nothing blocking it; when White walks over to it there is now a board covering the hole that he has to kick through to break it.
Corrected entry: When Bud visits Lynn (The scene where he punches her), as he walks up to her house, you can see a sunny area behind him, even though it is raining heavily.
Corrected entry: License plate numbers are incorrect. In the 1950s, there were 5 digit plates, but in the film, there are 6 or 7, like nowadays. (00:37:40)
Corrected entry: When Bud is talking to Lynn about Susan Lefferts, Lynn says something to the effect that Susan "came on a bus with dreams of Hollywood, and this is how they turned out." But Bud later visits Susan Lefferts's mother, who lives in Elysian Park. That leaves three possibilities: One, Susan's mother originally lived somewhere other than Hollywood, and then moved there at some point. Two, Susan lived with someone other than her mother before coming to Hollywood. Three, the bus Lynn was referring to was a city bus - which would have travelled about six miles.
