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.
