Continuity mistake: When Christy walks into Station 51's kitchen, the bag strap is on her shoulder, but close-up it is gone, only to be back next shot when she removes it a moment later.
Revealing mistake: In at least three episodes, which include 'Saddled', 'Peace Pipe' and 'Women', the same corner restaurant/hot dog stand (with a striped orange/white awning and green vinyl bar stools) is featured. That would be fine, if it weren't for the fact that in each episode the street it is located on has a different name and different cross streets. It is obviously a set on the Universal Studios lot.
Peace Pipe - S2-E5
Continuity mistake: When DeSoto and Gage arrive at the corner shop for the gum ball machine rescue, in the overhead shot the front end of the parked RV is beside the lamppost, but in the next shot half its body is past the fixture.
Continuity mistake: At the stationhouse, when DeSoto and Gage are discussing the detective, in the shots facing Gage, DeSoto holds a cup of coffee in his hands, but in the shots facing DeSoto his cup is on the table.
Dinner Date - S2-E10
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 joins Gage at the kitchen table they discuss Gage's bright idea of rodeos. In all the shots facing DeSoto his hands are clasped together with the coffee cup on the table, but in all the shots facing his partner, he's holding the cup of coffee. The magazine ends up under DeSoto's arms between shots as well.
Continuity mistake: The shaving foam on DeSoto's face changes between the face-on shots and the reflection shots, and in the reflection he shaved from cheek to chin, but in face-on shots only to the neck.
Continuity mistake: When DeSoto starts to crack about what's upsetting him, Gage places a mop beside another mop, up against the door and it falls over. Next shot both mops are upright and in different positions as well.
Other mistake: When Roy gets off the phone and heads to the squad, Johnny follows him wanting to know who he was talking to, and after Roy tosses Johnny a rag to help wipe down the squad, we hear the dispatcher ask, "Foam 27, what is your location?" but subtitles read, "Phone 27, what is your location?" Subtitles from Universal Studios 2010 DVD.
Other mistake: While 51's guys are at the accident scene by the freeway on-ramp, when Roy's standing on the ladder and says the car door's jammed, Captain Stanley tells Chet and Marco to get the Porta Power, but subtitles read "Jack, Marco, we need the Porta Power," even though there's no character named Jack. Subtitles from Universal Studios 2010 DVD.
Continuity mistake: Gage and DeSoto arrive at the apartment complex, home to the guy trapped in the couch. They park the vehicle and walk on the gated balcony to the apartment. In the exterior shot, when they enter the doorway the inside wall to their left is bare and the corner of the balcony's iron gate is to the doorway's left. Next interior shot, now there is a large painting on that previously bare wall and the iron gate is directly in front of the door. When they leave, their vehicle is farther away, positioned differently.
Continuity mistake: When the guys begin to use the pulley system to lift the car engine off the injured man, the women stand to the officer's left (viewer's right), but in the next close-up it is switched, then back again in the wideshot.
Continuity mistake: After the guys lift the car engine off the man and Kelly maneuvers the car backwards, the same close-up of the officer and two women that was shown a few shots earlier is shown again, even though the car is now moving farther back.
Peace Pipe - S2-E5
Continuity mistake: After Gage catches fire from flammable hose 'water' and removes his jacket outside, when DeSoto walks to his Engine Co., the gloves he holds switches hands between shots.
Other mistake: During the rescue at the studio, when Roy tells Marco and Chet that they need to latch up the wagon before it pulls the stuntman over the falls, we hear the dispatcher say, "Copter 10, respond with Engine 69," but the subtitles read, "Trucker 10, respond..." There is no such thing as Trucker 10. Subtitles from Universal Studios 2010 DVD.
Other mistake: After Marco offers Boot the ground beef while the guys are trying to figure out what's wrong with the dog, the tones drop and we hear the dispatcher say, "Station 51, Engine 95, Foam 27," but the odd subtitles read "Engine 95, Phone 27." Subtitles from Universal Studios 2010 DVD.
School Days - S2-E14
Visible crew/equipment: When Roy walks into the kitchen late at night, while Billy's alone on the couch studying about emergency medicine, there are moving shadows on the floor towards the left of the screen.
Peace Pipe - S2-E5
Visible crew/equipment: Just after the drunk driver is loaded onto the ambulance, when Roy tells Johnny about Debbie's pulse and respiration, and that she's in bad shape, then also when Roy tells Captain Stanley to make it quick, a crew member sitting atop a ladder with set lighting beside him are visible in the background.
Continuity mistake: While Brackett is with Ken in the ER he's wearing a blue/white striped tie, and when he calls Ken's doctor the tie is tied differently, but then it's tied the original way.
Peace Pipe - S2-E5
Other mistake: When John and Roy are up on the scaffold with the injured man during the sniper fire, from the time they unfurl the large tarp and tie it off to the beams the sniper fires zero shots at them, zip, but later at the station Chet asks John, in all seriousness, if he got a good look at the tarp before they left, and tells him that the tarp looked like Swiss cheese due to the sniper fire.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.
Bishop73
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.
