Visible crew/equipment: Lauren Bacall and Marlowe go back to Arthur Gwynn Geiger's house at the end of the movie and the camera's shadow falls across the lamp as he walks up to the phone. (01:45:55)
Continuity mistake: When they meet up at Geiger's house at the end of the movie Eddie Mars says to Marlowe, "What are you gonna do about it?" as he leans back onto the couch. In the next shot he's sitting straight up facing him. (01:50:45)
Continuity mistake: Eddie Mars is shot several times as he runs outside the house but when he falls back threw the door there are no bullet holes or blood on his jacket. (01:51:40)
Continuity mistake: After Eddie Mars falls back threw the door bullet holes are sprayed across Geiger's door. A few seconds later Marlowe kicks the door shut and the bullet holes are not in the same place on the back of the door as they were before. (01:51:55)
Continuity mistake: When Philip Marlow goes back to his apartment the camera zooms in on the card with his name and profession on the door right below the apartment number, yet when he opens the door when Vivian comes, the card is missing.
Character mistake: When Lauren is playing roulette, she has $14,000 worth of chips sitting on red - if she wins, she gets double, $28,000; and if she loses, she loses all of the $14,000 - but the croupier is troubled and says to Lauren that she hasn't got enough to cover the bet, which is ridiculous; all her $14,000 chips are sitting on red, what more does she need? Even the head croupier is called in, and, after much chatting, all the other players are asked to take their chips away as only Lauren is playing this round, which is ridiculous: All they have to lose is $28,000; that's nothing for them.
