The Promise - S3-E11
Continuity mistake: When Johnny's on the ledge with Richard, just as Richard awakens he knocks the penlight out of John's pocket, but when Roy joins them on the ledge the penlight is back in Johnny's pocket, beside the green pen.
The Promise - S3-E11
Continuity mistake: When Bo goes to Richard's room for the first time, in the view from inside the patient's room, as Bo pushes open the door we can see the hallway behind him, and there's a perpendicular wall beside the door. This wall does not exist when he visits Richard the second time, because there's a hallway leading to the elevator outside of Richard's door.
The Promise - S3-E11
Continuity mistake: When Bo Jensen goes to Richard's room for the second time, as he pushes open the door we can see there's a wall perpendicular to the door, but when Bo is in the room there's a wide widow covered with curtains where that wall was. The window with curtains can also be seen in the exterior shots, when Richard jumps out the hallway window.
The Promise - S3-E11
Continuity mistake: After Johnny finds the missing mechanic, when he turns him over from his stomach to his back, Johnny's wearing a watch on his left wrist, but in the closeup showing Johnny's arms turning the catatonic mechanic over, Johnny's watch has vanished.
The Promise - S3-E11
Continuity mistake: When Roy and Johnny try to subdue the out-of-control patient on Rampart's ledge, after Brackett tells them that he'll go to x-ray right away, Roy's helmet is off, but in the overhead shot it's on his head, then in the next shot Roy puts it on his head.
The Promise - S3-E11
Continuity mistake: When Station 51 is dispatched to the people trapped in the house, Johnny and Roy clear away all the tumbleweeds from the front door, but in the next shot facing the door there is another huge tumbleweed in front of it.
The Promise - S3-E11
Visible crew/equipment: When Paula walks in the kitchen's back door holding the dog, in the overhead shot the actor's black tape mark is visible on the floor by her feet, which was not there when Johnny had first seen her.
Revealing mistake: After the two drivers from the traffic accident walk off holding hands, and Johnny tells Roy what happened with Barbara, while Roy explains "body-language" to Johnny, we can see the white tape with "Kevin" inside Roy's helmet.
Visible crew/equipment: After the squad and engine pull up to the theater, when the manager of the band tells Johnny about the musicians wigging out onstage and then 51's guys follow him, the reflections of the camera dolly and moving crew members are visible on the surface of Squad 51.
Continuity mistake: After the cropduster crashes, when Roy and Johnny pull the pilot out of the overturned aircraft and begin working on him, Johnny's medical holster with penlight, forceps and scissor is clipped at his right hip and the other holster's at his left hip, but when Johnny shouts to Chet about giving the victim oxygen, Johnny's holsters have switched sides.
Continuity mistake: When Roy tells Johnny to call Barbara, who heard something that he didn't even say at the movies, in the view from the kitchen Engine 51 is not in the apparatus bay which means everyone else is on a run, but when dispatch drops tones we hear Captain Stanley respond KMG365, and then see the engine parked in the bay.
Visible crew/equipment: At the horse ranch, after Bill falls off the horse again while the squad is chasing after him, when Roy kneels beside Bill we can see the shadow being cast by production equipment, presumably the reflector screen, on the ground behind Roy. Then after John checks Bill's ears and pulse, just as he contacts Rampart for the second time, we see movement which looks like a sleeve on the right side of the screen, beside John.
Continuity mistake: When the guys are eating dinner talking about marriage, John's glass of milk is half full in the shot from behind him, but when Barbara calls the station and Captain Stanley answers the telephone, John's glass is nearly full in the shot facing him.
Character mistake: When Johnny and Roy respond to the 'possible injury at the horse ranch', after the guy who was knocked unconscious gets back on the horse, Johnny tells Roy, "Why don't we stick around for another few minutes, unless we get another call." They did not contact the dispatcher that the squad's available, so they would not even be dispatched to another call, since they're already on that run.
Character mistake: When Johnny is about to tell Roy what the problem is, the dispatcher drops tones and says "Station 51, Engine 36, Truck 116, small aircraft in trouble.," but when Captain Stanley responds we hear him say, "Squad 51, 10-4...," even though he should have said, "Station 51, 10-4...," because both Engine 51 and Squad 51 were dispatched.
Continuity mistake: While Roy and Johnny are working on the guy who fell from the horse, since Roy's hands are busy he has the IV line dangling from his mouth before setting up the patient's IV, and in wide shots the cannula is dangling at the left side of his mouth, but in closeups the IV line and cannula have switched sides.
Deliberate mistake: While Squad 51 is chasing after Bill, who's slumped over in the saddle on the run-away horse, one of the shots of Bill from inside the squad is a flipped shot. Note the landscape, as well as the shadow being cast on Bill's right instead of his left.
Visible crew/equipment: At the horse ranch, after the man falls off the horse John and Roy rush over, and as Johnny leans over him the bulging outline of the lav mic transmitter is visible on the back of Johnny's jacket.
Continuity mistake: After bringing in the atropine overdoses from the daffodil bulbs, in the shot from inside the treatment room when Roy and John leave treatment 3, which is opposite the nurses' station, they turn left to head towards receiving, but next shot they're walking from around the corner in the hallway, then pass that door they just left from.
Audio problem: After John starts telling Roy about how he and Barbara went to a movie, when Squad 51 is dispatched to 'man unconscious at Observation Park', we see a closeup of Roy in the squad as he puts the gearshift into drive, and then we hear the audio of the ignition being turned on.
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.
