Continuity mistake: In the restaurant Marlowe sits looking down at the table as Lauren Bacall talks about General Sternwood and says, "he considers the case closed". She's holding her pocketbook with the strap between the first and second finger of her left hand but in the next shot the strap is in a different position near her left thumb. (01:02:00)????
Continuity mistake: As they have drinks in the restaurant Marlowe says to Lauren Bacall , "I don't know how far you can go" and she replies, "A lot depends on who's in the saddle" and he goes from having his right hand next to his drink to having both hands around his drink between shots. (01:03:35)????
Continuity mistake: Marlowe tells Joe Brody to get the pictures of Carmen Sternwood and he walks over to his desk that we've seen in an earlier shot. No one goes near the desk but a different set of books are between the horse head bookends, and they keep moving throughout the scene. (00:48:40 - 00:52:20)????
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)????
