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)????
Continuity mistake: In the DA's office Marlowe says to Capt. Cronjager, " That's all, I was in a tough spot, I was probably wrong but I wanted to protect my client" and Marlowe's hat is on the DA's desk right next to his left arm. In the next shot an ash tray with a smoldering cigarette is next to his left arm (1945 Version on DVD). (01:04:45)????
Continuity mistake: After taking Carmen Sternwood to her bedroom, Norris the Sternwood's butler helps Marlowe put on his over coat as he prepares to leave. Marlowe wasn't wearing it when he came into the house though and there's no indication that he had it in Carmen's car because when they left Arthur Gwynn Geiger's house he didn't have it on. (00:27:15)????
Continuity mistake: Marlowe goes into Geiger's house again to snoop around and he finds that Geiger's dead body has been removed. As he stands over the spot where the body was his shadow falls right on the bloodspot. In the next shot of him kneeling down and touching the blood stained carpet there's no shadow. (00:28:00)????
