Continuity mistake: When Johnny and Roy are at the apartment building with the broken elevator, Roy's watch is gone when they climb the steps, but he's wearing the watch when they enter the apartment, then it vanishes when they head back down. That watch reappears again, disappears and reappears until they go back up to the apartment for the second time.
Visible crew/equipment: When Gage and DeSoto are on their first run (the mother-in-law), they phone Rampart's base station. When Dixie opens the door to answer the call, her mark (strip of black tape) is visible on the floor just as she steps on it.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
