Other mistake: When Station 51 is dispatched in the middle of the night to the industrial fire, the dispatcher says "Time out 1:07," but later at Rampart after Brackett tells Johnny to stay the rest of the night because of the exposure to the radiation, we hear the voice on the PA announce, "Visiting hours are over" even though it's supposed to be at least 3:00 AM.
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.
Other mistake: When Squad 51 is dispatched to "possible heart attack" the address is "91st and Formosa" (the 'Black Tower' can be see behind the Chevron sign when the squad rolls up), and later when they're dispatched to "person caught in mailbox" the address is "Beverly Blvd and Main." What's funny is that the two incident scenes are filmed at the same corner of the intersection, with Universal's 'Black Tower' nearby. Have a look.
Above and Beyond... Nearly - S5-E20
Other mistake: After Dixie gets the call from the dental clinic about the possible MI, she and Brackett take the elevator located at the nurses' station and head up to the dental clinic on the third floor. Problem is that the ER is only a 2-storey building, so that is quite impossible.
Other mistake: When the woman from the salon is brought into the treatment room she's unconscious, but as they transfer her from the ambulance stretcher to the hospital gurney, she lifts her left arm from under the stretcher bar and then also positions it on the gurney.
Other mistake: While Johnny and Roy are with the possible heart attack, they've patched her in for the EKG, and in the base station room Brackett looks at the EKG strip and the unit's monitor, then it cuts to a closeup of the Datascope monitor, even though the Datascope is not actually in the ER's base station room.
Other mistake: After Roy has found the location of the boy trapped in the collapsed building, Captain Hammer gets on the handy-talkie and says "Engine 51, Stoker," but oddly enough the subtitles read, "Agent 51, Stoker." Subtitles from Universal Studios 2010 DVD.
Other mistake: When the dispatcher drops tones for the structure fire, he calls on Station 51, Engine 27, Engine 32, and Truck 105. Once there, Captain Stanley tells the dispatcher to send a second alarm, then hear him call on Station 19, Truck 98, Truck 34, and Battalion 43. However, the only ones at the fire with 51 are Engine 9, Engine 17, Truck 17, and two men with helmets from 20, even though dispatch did not call on any of them, and of all the companies that were called to the fire, none were there, except for 51.
The Wedsworth-Townsend Act - S1-E1
Other mistake: When Squad 10 is dispatched to the the high-voltage electrocution, Tony opens the bay door, but the closeup we see is actually the same closeup of the hand cupping the switchplate that was shown earlier, when dispatched to the nighttime factory fire.
Daisy's Pick Blind Date - S4-E7
Other mistake: When Squad 51 is dispatched to "man needs assistance", in the exterior shot as the squad rolls out of the apparatus bay we can see Engine 51 still inside the bay, but the real Station 127's engine is parked right beside the station house.
Greatest Rescues of Emergency - S7-E5
Other mistake: After getting their promotions, Roy and Johnny start recalling their history together and when Johnny remembers joining the paramedic program he says he was at 8's, but Johnny was at 10's and it even shows the clip from the show's pilot where Johnny's standing behind Engine 10 talking with his Battalion Chief. The filming of the show's Station 10 was done at the real Station 8. As an aside, the real Station 8 was also seen in the 1950's TV show Rescue 8.
Captain Hook - S6-E8
Other mistake: While Roy, John, and Chet are talking about the party, and how emotional it all was, we hear Hookrader say, "Lopez," just as he walks into the kitchen where Marco Lopez is sitting, but the subtitles read, "Hello, guys."
Captain Hook - S6-E8
Other mistake: When Johnny and Roy rappel down the cliff to the downed police traffic helicopter, Johnny gets on the HT and says, "All right, Cap, this is HT 51..." but the subtitles actually read, "Hi, Cap, this is HE 51..." Then when they reach the chopper, Johnny says, "There it goes," and Roy says, "Okay, I'll take this side," but the subtitles reverse who says both lines. Subtitles from Universal Studios 2010 DVD.
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.
Other mistake: When Brackett asks Early to see the patient (Jaime Farr) who claims he can't move his arm because of a curse, Early walks into treatment 5, but in the shot from inside the room we can see that they're in treatment 2.
Other mistake: When Roy and Johnny are with the woman whose hand is caught in the mixer, we can see tape on the side of the stand mixer (Sunbeam) as well on the food containers, covering all their brand names.
Other mistake: Jamie Farr appears in 2x19 "Boot" as Alan Austen, the guy who claims that he can't move his arm because of a curse, but he's mistakenly listed in the credits at the end of this episode.
Other mistake: On the first run of the Ward LaFrance we hear the dispatcher say, "Wrecking yard fire," but subtitles read, "Working yard fire," and as soon as Engine 51 rolls up on scene Mike turns to Captain Stanley and asks, "Light water?" but subtitles read, "Do we got water?" Then we hear the dispatcher say, "Repair 3, call Station 8," but subtitles read "Return 3..." Subtitles from Universal Studios 2010 DVD.
Other mistake: On scene at the plane crash, just as Roy and John are about to head down to the aircraft we hear the dispatcher ask, "Foam 23, what is your location?" but the odd subtitles read, "Phone 23..." Subtitles from Universal Studios 2010 DVD.
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.
