Revealing: Right at the start of the movie, Tom Ewell is in Central Station kissing his wife and son goodbye. When they are just about to leave, watch a kid on the left of the screen. He can't help staring at the camera.
Continuity: Tom Ewell turns the record player off twice toward the beginning of the movie. He turns it off before the janitor comes in, then he turns it off again after the janitor leaves.
Continuity: In the very last scene Marilyn Monroe throws Tom Ewell the shoes he forgot to put on. He thanks her and waves, with one shoe still held in his hand. He turns round and walks away, with both shoes on.
Other: When Tom Ewell's character trips over a roller skate for the second time, as he approaches the skate rolls into his path from outside of the frame. He was living alone. What could have possibly propelled the skate all of a sudden?
