Character mistake: The voice tells Tom that the alarm deactivation code is 47223. However, when Tom enters the code subsequently to deactivate the alarm, he only enters "4723." You can tell he doesn't enter a fifth digit because the keypad chimes each time a digit is entered.
Nowhere Man (1995)
1 character mistake in season 1 - chronological order
Starring: Bruce Greenwood, Megan Gallagher, Marvin LaRoy Sanders
Audio problem: The scene where Tom goes to his home, to be confronted by his wife, the dog, and another man holding a shotgun. The other man has just told Tom that either he walks away or he gets shot in the leg. There is then the sound of the dog growling for several seconds, but the dog's mouth/muzzle isn't moving, and it isn't growling.
Thomas Veil: The truth is unforgiving, don't shoot the messenger.
Trivia: Intended to be a homage to the cult TV shows "The Fugitive" and "The Prisoner."
