Continuity mistake: When Roy brings the injured tanker driver into the ER, the attendants wheel the stretcher down the hallway passing treatment 3, and after Roy asks Brackett and Early a pointed question about the trucker's condition, the doctors also walk down the hallway passing treatment 3, in the direction of the nurses' station. But then we see that Early and Brackett are with the patient in treatment 3, which is right beside the ER's receiving entrance.
Continuity mistake: When Station 51 is being dispatched to the brush fire, there's black tape on the chrome trim of the squad's lightbar, but when Squad 51 arrives on scene the black tape has vanished. Then later at Rampart, after Brackett calls Roy a hose jockey, the black tape is back, but vanishes again when they rescue the injured looter.
Cook's Tour - S1-E4
Continuity mistake: While Early is trying to remove a young boy's hand from a vase, in the shot from inside the room he's in treatment 3 with a windowless door, but when he steps into the hallway and asks Sharon for ice cubes he's at treatment 5 with a window on the door.
Revealing mistake: At the end of the 'crashed plane in a tree' rescue, Tom falls upside down in front of Roy and John, who are standing on branches way high up in the tree. Then just as the scene ends and the screen fades out, we can still see Gary Crosby (Tom) having fun jumping hard up and down on that "tree branch" that he's now also standing on, and Randy Mantooth starts cracking up.
Continuity mistake: When the babysitter runs into Rampart with the child who swallowed phenobarbital pills, Brackett picks the boy up and carries him into treatment 5 (window on door), but in the following shots from inside the room we can see they're actually in treatment 2 (windowless door and set up differently). Then after they place the pacemaker Dixie leaves the room, and in the shot from the hallway she's coming out of treatment 5.
Continuity mistake: While Brackett is treating the man who was in a fight, it cuts to Early walking down the hallway, and in the shot from the hallway he's entering treatment 4 which is beside the nurses' station, but in the next shot from inside the room we see he's actually in treatment 2, the one beside the receiving entrance.
Continuity mistake: After Sharon calls out Dr. Early's name in the hallway, because paging him didn't occur to her, when she finds Early they walk into treatment 2 in the shot from the hallway, but in the shot from inside the room they're all in treatment 5, not 2.
Continuity mistake: When Roy breaks the key in the squad's ignition, while he's holding the broken piece in the two wide shots there's something dangling from the key's hole (another key/keychain), but in the closeup it's just the broken bit in his hand.
Continuity mistake: While Johnny and Roy are standing near the nurses' station, Johnny admits that he promised to take care of Paula's dog, and when Johnny turns his head toward Dixie and Brackett we can see the base station behind him, and in the next shot when Dixie and Brackett walk over, a clipboard has suddenly appeared between the telephone and Biocom EKG unit.
Revealing mistake: After Paula's car door is pulled open, when Roy leans her head back in the shot from behind him, we should be able to see out the right rear window, but the view has been deliberately blacked out from this POV.
Continuity mistake: After Paula's taken in the ambulance, when Roy heads to the wrecked car and pushes the driver's backrest forward revealing Bonnie in the back, we can see that the passenger side door is closed, but in the next shot the passenger side door is wide open.
Continuity mistake: When Johnny's on the Biophone establishing contact with Rampart, there's a closeup of the GE telephone at Rampart's base station, and behind it we can see the tape machine switch is turned to the right, in the 'on' position, but when it cuts to Dixie walking over and responding, the tape machine is not on yet.
Continuity mistake: On scene at Paula's car accident, her houndstooth blazer is lying over the backrest of the front passenger seat, but when Captain Hammer opens the passenger side door it vanishes, then it continues to reappear, disappear, and change position in following shots.
Continuity mistake: When 127 hoses down the underside of the overturned trailer, we should be able to see the water spray while John and Roy try to get to the trapped driver in the cab, but we don't even though we hear the audio of the hosing.
Revealing mistake: When Roy and Johnny are in the radioactive lab, loading the unconscious doctor with severe radioactive poisoning onto the stretcher, note that the unconscious doctor is lifting his own left arm, and moving it onto the stretcher so it's resting beside him properly.
Continuity mistake: While Squad 51 leaves the brushfire area with the looter (Tony Dow), when Johnny requests a water drop the helicopter pilot says that he's Copter 2, but the footage we see of the chopper flying overhead is of Copter 14 and Copter 10.
The Wedsworth-Townsend Act - S1-E1
Continuity mistake: When the Battalion Chief's car arrives on scene at the factory fire, he and the driver get out of the car, then it cuts to shots as they both stand beside the wall while the Chief talks to dispatch over the HT, but a few shots later we see the driver just getting out of the car as Engine 36 passes.
The Wedsworth-Townsend Act - S1-E1
Continuity mistake: While Roy shows John the squad's right, front compartment, in the closeup of the Datascope a clipboard/notebook with a stack of papers suddenly appears atop the OB kit, which vanishes again in the OB kit's closeup.
The Wedsworth-Townsend Act - S1-E1
Visible crew/equipment: When Roy and John walk into the apparatus bay they stand behind Squad 51, and in this wide shot we can see that the floor area around the squad has nothing on it, but when Squad 51 is dispatched to 'traffic accident with injuries', there is now a long black tape line on the floor, near the front tire.
The Wedsworth-Townsend Act - S1-E1
Visible crew/equipment: When Squad 51 is dispatched to 'traffic accident with injuries', while en route as Johnny says "Hang a left, I know a shortcut," the shadow of filming equipment becomes visible on the hood of the squad.
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.
