Continuity mistake: When the paramedics and the rest of the firemen gather round the failed pacemaker patient, their positions change and in DeSoto's close-ups the Captain isn't seen (for the camera angle's sake), although in other shots he's right beside Gage. As an aside, note when Captain Stanley first first gets off the engine and trips in the background.

Continuity mistake: When DeSoto and Gage are in the pool with the little girl whose arm is stuck in the drain, their shoes and pants are soaked. However, just after Gage gets off the Biophone, his shoes and pants are completely dry, and then when the pool has been mostly drained both DeSoto and Gage are dry.

Continuity mistake: When Johnny and Roy are standing by the squad outside Rampart, talking about the man in a hepatic coma, both ER doors are wide open, but when the woman drives up and then shouts that she needs help both doors are closed, and this continues a few times depending on the angle of the shot.
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.
