When Joey sits down at Mrs. Simpson's table, her hands jump about between shots.
When Joey inveigles his way into employment at Ned Galvin's Nightclub by his rendition of "I didn't know what time it was", out front in the audience is a dating couple whose evening together is somewhat frosty. During the song the ice melts and eventually they are seen cuddling. Unfortunately, Joey's magic spell is short-lived, as, at the song's conclusion, the same couple are again seen in long-shot, but alas they are once again sitting on either side of the large round table.
When the butler approaches Mrs. Simpson's table to announce that Joey wants to see her, she has her hands on the table. The subsequent shot shows her lowering the juice glass, just after to drink a little.
After Linda sings, Mrs. Simpson talks to Joey with her left hand touching her chin. In the following shot her hands are on her handbag. In the same scene Joey rests his left hand on his leg, but between shots his left hand appears on the back of the chair beside him.
In the beginning of the film, Joey is led by two policemen who hold him by his arms. When they approach the train, Joey's raincoat lapels are untidy. Next shot they are neat.
When Vera Simpson is singing "Bewitched" there is a very obvious mismatch between her lips and the words as she is turning away from the window.
In the opening scene, Joey is escorted onto a train leaving town. Spengler's Fish Grotto is visible in the background, placing this in W Berkeley (though the police car reads "Gold City.") The train is headed north. Next, we see Joey exiting the train heading towards the "Ferry to SF" which would've been one of the Oakland stations, which is just a few minutes South of Berkeley.
