Goofs

When Dan asks film reviewer "Mr. Blair" into the men's room at The Cocoanut Grove to "discuss" his latest review, all of the stall doors are closed. After Dan forces him to eat his review, the third stall door is open (no one enters or exits the room during this scene).

After the robbery of the wealthy woman's home, the paper says a maid was struck and seriously injured, and later in Dan Quigley's office, they're still talking about a maid who screams. Later, when the guy who actually hit her comes back scared, he says the butler died.

The owner of the house where Dan was taken after the "car accident" was Mrs. Wilbur Marley. This was the house where the maid was "slugged". The butler who "croaked" was "on the Crosby job".

When Dan first meets Lois in her dressing room, they are briefly interrupted by George, who hands Lois a magazine. He tells her that she is on the cover of the magazine called "Filmed Life". They use the real fan magazine Photoplay as a prop. The Photoplay title is clearly shown when Lois is looking at it.

When the gang is chasing Myra and Dan (and the cops are chasing the gang), car tires squeal on the dirt road.

Near the end, Dan gets released from jail on bail and then is in the car chase and shootout. After the car crash, he and Myra take refuge behind a large tree, whereupon Dan produces a mysterious handgun (He couldn't have had it in jail, and Myra never had one.) and returns fire at the gang and subdues Spade.

When Dan's former gang approaches the car offering a tour of movie stars' homes, they walk through the shadow of the boom microphone; it initially is seen on the street at their feet, then it rolls up all four as they walk to the side of the car.
