Continuity mistake: At the beginning of the film (in the short story about the man who jumps off a building and is shot and killed on the way down), the bullet is supposed to have killed him instantly, but the actor still puts his hands in front of his face very quickly when he hits the window cleaner's net a few floors down.
Continuity mistake: The length of Claudia's hair changes during what seems to be a period of time shorter than a day. A similar thing happens with the colour of the bartender's lover's hair - it changes from almost blonde to dark brunette.
Other mistake: When the nurse opens the door you can see the big dog looking at the camera; it does this a few times until someone calls him away. Once when the door is opened you can see the person coming in giving a treat to the dog.
Factual error: In the beginning vignettes there is a scene of the pilot playing blackjack in the casino. He's holding his cards, which means he's playing at a table with a two-deck shoe. But the shoe on the table is very clearly at least a six-deck shoe.
