Revealing mistake: When Johnny and Roy are in the squad heading to Rampart after freeing the girl's toe from the bathtub, they get dispatched to 'possible electrocution' and we can see the white tape with "Kevin" inside Roy's helmet. (00:37:30)
How Green Was My Thumb? - S3-E17
Revealing mistake: When Roy brings the man with a laryngeal obstruction into the ER and is taken quickly to treatment 1, his head is tilted back and Early places a laryngoscope into the patient's mouth and says that he sees the obstruction. The problem is that we can see that the laryngoscope is actually at the side of the patient's face. Then, when Early uses the forceps to remove the obstruction, once again we can see that it does not go into the patient's mouth.
Other mistake: While John is searching through the papers for the receipt, when Roy takes the milk carton out of the fridge he pours some into a glass and some ends up spilling onto the floor, we can see there's black tape on the milk carton covering the brand name.
Visible crew/equipment: At the refinery fire, after the stokes is loaded onto the snorkel and then John and Roy climb in, two shots after Captain Stanley's closeup, in the shot tilting up at the descending snorkel basket, a crew member who is crouching down can be seen on the tower behind it (presumably it's the second cameraman shooting all the footage from that angle).
Other mistake: On site with the boy on the ledge, when Truck 85 raises the aerial ladder Roy stands by and waits to go up with Johnny behind him. Both Roy and Johnny are the only ones not wearing their turnouts, and both of their watches are on their left wrists, but when 85's aerial apparatus operator says "Desoto, up the aerial," the bare arm we see beside him is wearing the watch on his right wrist. This is not a flipped shot.
Revealing mistake: After Gage gets bitten by the rattler, when the driver of Tractor 2 begins ascending the cliff, there is a nice close-up as he passes and this young stuntie is most certainly not the older driver seen in this scene. Not to mention the watchless driver suddenly acquires a black watch and a plastic face shield attached to the helmet.
Visible crew/equipment: When Squad 51 is dispatched to the "possible heart attack," just as the squad rolls up on scene, we can see its real license plate with number 70324H, instead of the prop plate number E999007.
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.
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.
Visible crew/equipment: When Roy and Johnny are with Dixie, they see the new unit and scanner at the base station, and when Roy walks over to it, the actor's white tape mark is visible on the floor where he stands.
Visible crew/equipment: When Johnny chases Harriet down the street, behind Johnny we see Roy backing up the squad to follow them, with nobody around, then when it cuts to the view from within the squad, the reflection of crew is visible in the driver's side mirror.
Visible crew/equipment: When Roy gets the little girl, Angie, out of the wrecked airplane and then places her in the Stokes basket, the outlines of the mic transmitter and wire are visible on the back of his shirt.
Continuity mistake: When Roy and Johnny are on the roof with Harriet, we can see the shadow being cast by the utility pole on the street down below, and when the police car shows up moments later that shadow has changed significantly. (00:12:40)
How Green Was My Thumb? - S3-E17
Character mistake: When Johnny is filling the radiator on the squad, he pays close attention to not over fill. After Chet comes in and asks a question to Roy, the alarm goes off, Johnny closes the squad hood, without pulling the radiator cap on.
Continuity mistake: In the opening scene when Johnny and Roy walk into Captain Stanley's office, Johnny's pack of cigarettes is in his right shirt pocket. As he and Roy are talking in the apparatus bay, the cigarettes are still in his right shirt pocket. When Johnny enters the kitchen after Roy, the cigarette pack has magically moved to his left shirt pocket.
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.
The Promise - S3-E11
Visible crew/equipment: After Squad 51 is dispatched to 'woman down', just as the squad rolls up in front of the apartment building we can see a bit of the camera's production equipment at the bottom left corner of the screen, which is then pulled quickly out of shot.
How Green Was My Thumb? - S3-E17
Other mistake: Eric Shea appears in "The Hard Hours" as Clyde, the boy who built a full size rocket, but he's mistakenly listed in the credits at the end of this episode.
How Green Was My Thumb? - S3-E17
Other mistake: During the refinery fire, while Roy is with Fernando the first victim, we hear Roy say, "It's OK, you're gonna be all right," but the subtitles read that Johnny says that. 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.
