Continuity mistake: After Squad 51 is dispatched to the 'injured man', when Roy and Johnny get out of the squad, Roy is not wearing his watch as they're walking to the victim while getting hounded by the dog, but in the next shot the watch is back on Roy's wrist as the dog chews on his pants.
Continuity mistake: While Roy and Johnny are with the back injury victim, his dog, Thadeus, runs off with the BP cuff, and when Roy chases him and falls into the pool, Roy's now wearing the water-type shoes, note the flat sole. Then when he and Johnny leave, the uniform shoes are back.
Continuity mistake: While Roy and John are with the man whose back went out, when Thadeus runs off with the BP cuff and Roy chases him, Roy has the stethoscope around his neck with the chest piece hanging down, but once Roy falls into the pool the chest piece is suddenly tucked down into the front of Roy's shirt.
Continuity mistake: While Johnny and Roy are with Dixie at the nurses' station, when Johnny looks for his paycheck in his shirt pockets, his right pocket's flap stays wonky, part in/part out in the closeup, but in the wide shot it's properly flat, then crooked, then straight again. Additionally, after Johnny finds the check in his wallet, he puts it into his left shirt pocket and points at Roy with his empty right hand, but when Early walks over Johnny has that check in right hand.
Continuity mistake: During the scaffold rescue, when John climbs onto the platform he takes off his gloves as he starts to check the victim, but in the wide shot the stuntman is still wearing his gloves as he checks the victim.
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.
