Continuity mistake: Earlier in the movie at Geiger's house, Marlowe calls Chief Insp. Bernie Ohls of the District Attorney's Office and the six digits of Bernie's phone number are 122-145. At the very end of the movie he's with Lauren Bacall at Geiger's house and again calls Bernie Ohls. This time he dials the same phone number at the DA's office but leaves off one digit 12-145 and the call still goes through. (00:59:55 - 01:52:10)????
Continuity mistake: Even though no one has gone near it, Lash Canino's steering wheel has been turned from the time he and Art Huck park next to the house to when he is shot by Marlowe. Not only is the shadow underneath different throughout the scene but the front wheels are turned all the way to the left after he's shot. (01:41:30 - 01:43:50)????
