Continuity mistake: Marlowe says to Lauren Bacall as she sits on his desk, "Then outside of what the woman said, you don't know any reason why they want five thousand dollars for it?". Lauren Bacall's right leg is higher than her left leg but then in the next shot they're reversed and her left leg is higher than her right. (00:34:30)????
Continuity mistake: Marlowe goes home after snooping around Geiger's house and we see the number 206 on his door with the words "Philip Marlowe, Private Investigator" underneath. Later when Inspector Bernie Ohls knocks on the door we see only the number 206 on it as Marlowe opens it. (00:29:20)????
Continuity mistake: After his car pulls up, Canino gets out and lights up a cigarette that he quickly throws to the ground when Lauren Bacal screams. Later, when Art Huck runs away after Marlowe shoots, we see that same spot again and the cigarette is now bent in half and in a different spot, almost under the car. (01:41:30)????
