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.

Continuity mistake: Eddie Mars pours Marlowe a drink and he puts the bottle down dead center on a tray on top of the liquor cabinet. He doesn't go near the bottle but later when we see it again it's right of the center of the cabinet, and in the last shot of it it's to the left of the center of the cabinet. (01:08:20 - 01:09:15)????
Continuity mistake: Lauren Bacall walks into a restaurant, and sees Marlowe at the bar with his head tilted back as he finishes his drink, and says, "Hello". The guy to the right of Marlowe is looking at the bartender but in the next shot his head has turned ninety degrees as he's now talking to his friend. (01:00:10)????
