Continuity mistake: When Fat Sam's gang sings 'Bad Guys', just after Snake Eyes says "Look at me, I'm dancing.", a broomstick appears to the right of Mario's barber shop which is not in the previous shot. (00:31:00)
Revealing mistake: When Tallulah and the girls are acting in the Fat Sam's Grandslam song look at Tallulah as they sing the 'Ra da da da da da' bit. She looks straight into the camera.
Continuity mistake: After the song "Tomorrow" Bugsy and Blousey are in the cafe. Blousey has a drink and it has two straws and one spoon. The spoon keeps disappearing.
Continuity mistake: Moments before Blousey Brown comes to Fat Sam's place for her audition, we see Tallulah kiss Bugsy in the centre of his forehead and leave a lipstick mark. A few moments later, however, the mark is much further over to the left hand side of his forehead.
Continuity mistake: When Fat Sam's gang sings 'Bad Guys' they take off their hats, revealing that their hair is out of place. In the next shot their hair is perfect again.
Continuity mistake: At the auditions, the Can Can girls fall through the stage, ripping a large hole in it. When Blousey comes on, straight after, the destroyed scenery is perfect again.
Continuity mistake: When Blousey and Bugsy are queuing up for the audition for the Lady Marley show, the girl behind her comes on before Blousey, even though she was behind Blousey.
Continuity mistake: When Dandy Dan's gang are getting ready to throw the pies at Doodle, if you look at Laughing Boy's pie, in the first two shots the white creamy stuff on top is all over the sides. In the next two shots the pie is neat and tidy.
Plot hole: Captain Smolsky only gets hit in the back with the plaster. So why, later on, is his entire body covered in hardened plaster, like a mummy?
Continuity mistake: When Fat Sam's gang are singing "Bad Guys", at the beginning of the song, just after they pick up the magazines, there is a close up of Snake Eyes. In this shot ("But don't it make your heart glad"), Snake Eyes does not have a toothpick in his mouth. In the next shot when it shows all four gang members he does have a toothpick in his mouth.
Continuity mistake: When Blousey and Bugsy are eating ice cream, note in Blousey's close-ups (from the front), her left hand is on the straws, near her face. In the shots of Bugsy when it shows Blousey from behind, her left hand is resting at the bottom of the glass. This also occurs with her right hand repeatedly.
Continuity mistake: When Dandy Dan's gang invade Mama Lugini's, they smash the pane of glass, and jump through. When he smashes it, only about half of the pane falls out. Next shot, the gang are assembled, and the pane is fully smashed.
Revealing mistake: When Lena enters, interrupting Blousey's audition, watch her closely. As she's doing her long and complex "Ill give you one more chance and them I'm out for good out out out" bit, she looks at the camera not just once, but quite a few times.
Continuity mistake: In the beginning, the gang are listening to the radio about the splurging of Roxy Robinson. Fat Sam, in his anger, shoots the white ball off the pool table. In the very next shot of him (when he says, "So tell me."), the white ball is back on the table as if he hadn't touched it.
Continuity mistake: During the song "My Name is Tallulah", Tallulah takes a dark-coloured beverage from a passing waiter's tray to drink. The scene then cuts to the dancers on the stage, then back to Tallulah who puts the drink back on the tray, but the remaining liquid in the glass is now completely clear, with no trace of dark residue.
Revealing mistake: This film is set in New York, yet most of the "down and outs" seen towards the end of the film have London accents.
Factual error: Cagey Joe's pullover definitely looks more 1976 than 1926.
Continuity mistake: When Fat Sam claps his hands after hitting Dandy Dan with a pie during the fight towards the end of the film, you can see that Fat Sam's face and suit are completely clean, but when we see Sam only seconds later the top of his suit and chin are covered with cream.
Continuity mistake: When O'Dreary and the policemen are lifting Captain Smolsky into the car after he has been covered in plaster they change position when the angle changes.
Continuity mistake: In the scene where Captain Smolsky is covered in plaster when the police car arrives Capt Smolsky is driving, O'Dreary is in the front passenger seat and there are two uniformed policemen in the back seat, but when the angle changes to the front of the car four uniformed policemen get out of the back seat.
Answer: He didn't have the money to pay the diner bill, so he called the operator, in the phone booth, to call the diner number to test the line.
