Continuity mistake: When Roy heads back into the dish to rescue Helen, he brings his remote with him. However, later on when the scene cuts to the kids watching their parents on the TV, the remote is seen on the table in front of them.
Suggested correction: The remote that Roy used to go back into the dish belonged to Roy's neighbor Murray who told Roy to take the remote and get Helen out after being mortally wounded at the club by a local gangster. This enabled Roy to go between channels while Diane and Darryl used their own remote to switch between channels to see everything that was happening on TV.
The remote from the neighbor was destroyed when they jumped to the French Revolution channel.
Continuity mistake: In the scene where Helen Knable is tied to a wagon on the train tracks; a tarp blows away to reveal that the wagon to which she is tied, is filled with crates of dynamite. During the next few cuts the tarp is back over the dynamite and then gone again.
Continuity mistake: During the music video for "Start Me Up," one of the dancers accidentally turns down the volume to the music, and we see the "Volume" status bar on the screen decrease. The dancers stop and act confused until one of them turns the volume back up again. The problem is, the "Volume" bar on the screen gradually increases, yet we hear the sound come back suddenly, as though someone just pressed a "mute" button.
