Continuity mistake: As Mona Mars and Marlowe talk about Eddie Mars on the left behind him, Marlowe's coat is draped over the couch. If you look closely only his coat is on the couch, but later when Mona storms out, a hat appears on top of the coat. At the end of this scene, the coat is knocked off the back of the couch and appears in a pile with the hat above. (01:37:25 - 01:40:25)????
Continuity mistake: Marlowe walks into Bernie Ohls' office and the sunlight coming through the blinds falls on the statue sitting above the bookcase as Bernie tells him, "You're to lay off the Sternwood case". They only speak for two minutes but as Marlowe walks out the sunlight falling on the back wall is in a different spot. (01:18:55)????
Continuity mistake: Chief Insp. Bernie Ohls hands the gun to Capt. Cronjager and we see that the lamp to the left of Dist. Atty. White is on. In the next shot if you look at the back of Dist. Atty. White's chair and the blinds behind him it's easy to see that the lamp is now off (1945 Version on DVD). (01:03:10)????
