When Alabama is being beaten up by Virgil, her face is bloodied early on. But when Virgil tosses her onto a half-wall and she slides across it, the blood vanishes from her face as she hits the wall (stunt double), and then reappears in the next shot.
When Clarence and Alabama arrive in Los Angeles, we see them driving along the freeway with the Capitol Records building in the background and the sun low on the horizon, indicating that it is evening. However, a radio announcer is talking about it being morning.
Elliott calls Lee on his car phone on Sunday. Lee tells him he will meet Clarence about Doctor Zhivago at the Beverly Ambassador on Wednesday at 3:00. Elliott hangs up and says that Lee will meet them at 3:00, but he doesn't say what day.
When Alabama enters the theater where Clarence is watching The Street Fighter, you hear dialog that takes place in the first scene of that movie. Once she sits down and lights a cigarette it cuts to the screen and the movie is at the climax.
In an establishing shot in front of the theater, supposedly in
Detroit, where Clarence is watching Shin'ichi Chiba movies, there is a street sign in the background which clearly says "Hollywood Boulevard". The theater itself is Vista Theater, a legendary smaller theater in East Hollywood.
Virgil beats up Alabama in her hotel room when she refuses to talk. After Virgil spots the suitcase of cocaine under the bed and grabs it, he prepares to shoot the kneeling Alabama. But when he sees her armed with a Swiss Army Knife corkscrew, he is amused and tells her she can have one shot. Alabama stabs Virgil in the foot with it, temporarily disabling him. However, a Swiss Army Knife corkscrew has a dull point, and like all Swiss Army Knife blades and tools, it will not lock in the open position. Therefore, unless Virgil was barefoot, in real life Alabama's stabbing attempt would have hurt her hand more than Virgil's foot. As soon as the corkscrew met the resistance of Virgil's shoe, it would have folded back into the knife, painfully pinching any of Alabama's fingers caught in between.
When Nicky Dimes and Nicholson are talking to their boss, Dimes says "So they bring the suspect to me and Nicholson, and we go to work on him". Nicholson interjects "...Nicholson and I," which is incorrect grammatically, but goes to establish the backwards intellectual pretentiousness of the character.
Drexl's left eye is blind and seen without a pupil. After Clarence shoots him, and Drexl is covering his face with his hands, Clarence commands him to open his eyes. We then clearly see a pupil present in the supposedly blind eye.
