Other mistake: When Station 51 is dispatched to the landslide, the engine company get into their turnouts and roll out, but in the next exterior shot as the engine drives past the camera, not only are the guys not in their turnouts, it's too obvious that none are 51's guys, and the one in Chet's jumpseat even leans forward. Presumably they're 127's guys. Also the light bar on the squad and the rotating light on the truck are not on.
Other mistake: When Station 51 is on scene at the landslide, there's a dresser on the grass in front of the house, and when the explosion occurs due to the broken gas main, in the closeups as Johnny dives to the ground there's what looks like a can of gasoline (used for the stunt perhaps) atop that dresser that wasn't there before, and it's also not in the wide shots as Johnny dives down.
Other mistake: After Brackett tries unsuccessfully to get O'Brien on the line to ask about the fish tank, it cuts to an exterior shot of Station 51, and we hear the dispatcher say, "All units responding with Engine 3 cancel," but subtitles read, "Four units with Engine 3 cancelled." Subtitles from Universal Studios 2010 DVD.
Other mistake: When the man injured in the manhole is brought to treatment 6, Early tells Roy to patch him up for an EKG, but the subtitles read, "Patch one from the EKG," and then Early tells the x-ray technician to do a skull and chest series, but the subtitles read, "Skull and chest searches." Subtitles from Universal Studios 2010 DVD.
Continuity mistake: When the guy who was injured in the manhole is brought into the ER, Dix tells them to bring him to treatment 6 (which is around the corner from the other treatment rooms, and has no color lines that run past its door), then we see him wheeled into treatment 6 in the shot from the hallway. However, in the next shot from inside the treatment room we can see they're not in treatment 6, but actually in treatment 1, note the red, green, and yellow lines on the hallway floor in front of its doorway, and treatment 6 has no color lines that run past its doorway.
Continuity mistake: When the TV catches fire in the kitchen, Captain Stanley unplugs it, and when it cuts to Roy running into the kitchen with the fire extinguisher, he passes Marco, who just ran into the apparatus bay. All of this while we hear Cap's voice telling Marco, who already ran out, to get the asbestos blanket. Then, in the next shot, Marco is still standing behind Captain Stanley in the kitchen.
Visible crew/equipment: After Station 51 is dispatched to the landslide, when Mike pulls the engine over on the side of the street, as Captain Stanley and Chet walk past the front of the engine, the cameraman's and crew member's legs are reflected on the windshield.
Character mistake: When the guy who was injured in the manhole is brought to treatment 6, he's transferred onto the ER's gurney and we see Carol taking his pulse, but then she tells Early, "Pulse 120, respiration 24," even though she never checked his respiration rate.
Continuity mistake: When Johnny's on the phone with Uncle Ernie about the new color TV, in the wide shot Johnny writes down the address of the warehouse, and puts the pen back in his shirt pocket. Then Johnny thanks Uncle Ernie, and when he hangs up the phone, in the next closeup the pen is back in Johnny's hand.
Visible crew/equipment: When the man who was unconscious for five minutes is wheeled into the ER, Morton has him taken to treatment 2, and when Carol is taking his blood pressure, the actor's tape mark is visible at her feet, under the gurney.
Visible crew/equipment: After Roy climbs down the manhole, he leans to the right (the second time), and when he points the flashlight down the tunnel on the right, the moving shadow of camera equipment is visible on the wall. We know it's not Roy's shadow because when he leans back to the left, that shadow is still moving on the tunnel wall.
Visible crew/equipment: When Engine and Squad 51 are at the cliff with the young unconscious boy, Captain Stanley calls in to dispatch, with Stoker standing beside him. The reflection of the camera crane and location set lights are visible in the side door mirror.
Continuity mistake: When the boy who fell over the cliff is brought into the ER, Dix tells them to bring him to treatment 3 and we see them at treatment 3's door, which is on the same side of the hallway as treatment 4, with the red line closest to it (hall has red, green and yellow lines on the floor which run the length of the hall) However, in the shot from inside the treatment room, they're not in treatment 3, but are actually in treatment 1. Note that we see treatment 4 directly across the hall, which means they're in treatment 1, and also see the yellow line is closest to the door which means it's on the opposite side of the hallway.
Continuity mistake: On the way into the treatment room with the unconscious boy, Gage is on the left side of the gurney holding the IV bag. Suddenly, he's on the right side, away from the bed.
Visible crew/equipment: When they wheel Dianne (the OD) into the ER it's one long continuous shot from receiving to treatment 1, shot from the POV of the patient lying on the stretcher. As she's wheeled into treatment 1, the camera faces Johnny so we can see up the hallway behind him, and the entire admitting desk and waiting area are all blacked out, and there are two men, one of which (possibly the director) is sitting on a chair facing up the hallway where Johnny is and the scene is taking place.
Other mistake: Brackett has Johnny and Roy in his office to listen to recordings on two cassette tapes - the first of 51's transmission with Rampart, and the second of 49's transmission with Pediatric Clinic. Brackett plays the first tape, pops it out and then plays the second tape. The problem is that when Brackett puts the first cassette tape back in the player, it's been rewound, even though Brackett never actually rewound the tape.
Visible crew/equipment: When Squad 51 is dispatched to the car on top of a roof, it cuts to John and Roy driving in the squad as John responds to dispatch, and the reflection of the filming vehicle is visible on the squad's surface.
Visible crew/equipment: When Roy and Johnny are dispatched to the plant with an 18 yr old whose arm is caught in a machine, the outlines of the mic transmitters are visible on the left side of Johnny's shirt, when he's on the Biophone, and on the left side of Roy's shirt, when he's putting the tourniquet on the 18 yr old.
Visible crew/equipment: After Dianne's OD, once she passes out and Johnny begins to work on her and inserts the esophageal airway, the bulging outlines of the mic transmitter and wire are visible on the back of Johnny's shirt.
Visible crew/equipment: When Roy and Johnny leave Rampart and are heading back in the squad, about 16:40 minutes in, as they are discussing whether Roy has told his wife about house hunting, you can see two signs on the ceiling of the squad's cab. The signs say 'Emergency Saturday 8PM Rehearsal Mark VI Prod'. Possibly they are magnetic signs for the squad doors so people don't mistake the squad for a real fire department vehicle? (00:16:20)
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.
