Other mistake: The USC game that Roy and Johnny are assigned to is supposed to be a sold-out game, but in closeup shots of the crowd around the guys, we can see that around the small crowd of extras used during the shoot, the seats are empty.
Fair Fight - S6-E5
Continuity mistake: At the start of the episode, we see the squad and engine pull back into the station, and one of the guys - it would be either Marco or Chet, is standing on the engine's tailboard motioning to Mike, who is driving backwards, but in the next shot both Marco and Chet are seated in their jumpseats as Engine 51 comes to a stop.
Fair Fight - S6-E5
Continuity mistake: At the structure fire, when Roy and Johnny rescue the man in room 22 by breaking the window, the door to room A is right beside them and we can see the axe mark on the door and the damage to the wall. When Johnny and Roy go back through the window to look for the missing Dr. Bennis, as Johnny uses the K-12, the door to room A now has many more axe marks and the damaged wall is far less damaged.
Continuity mistake: When Morton and Early are examining the guy with stomach pain and cramps, Morton's stethoscope is around his neck with the earpiece at his left and the chestpiece to his right, but in the closeup it's the opposite way around, then it's back to the original way.
Continuity mistake: While Johnny and Roy are with Dixie at the nurses' station, when Johnny looks for his paycheck in his shirt pockets, his right pocket's flap stays wonky, part in/part out in the closeup, but in the wide shot it's properly flat, then crooked, then straight again. Additionally, after Johnny finds the check in his wallet, he puts it into his left shirt pocket and points at Roy with his empty right hand, but when Early walks over Johnny has that check in right hand.
Continuity mistake: During the scaffold rescue, when John climbs onto the platform he takes off his gloves as he starts to check the victim, but in the wide shot the stuntman is still wearing his gloves as he checks the victim.
Revealing mistake: At the structure fire at an abandoned building, when Engine 164 arrives we see that it has distinctive markings beside the driver's side door and tire rim. When Engine 72 arrives the same markings are in the same place, revealing that it's the same engine and they used different magnetic number decals for the engine.
Continuity mistake: In the ER staff lounge, when Early and Dixie are watching The Game, there are five books lying on the TV with all their binding facing the right side in the closeups, but in the wide shots the books are facing the opposite way, with binding facing the left.
Continuity mistake: When the injured photographer is brought to the ER, Dix says treatment 7 and we see them heading into 7's door (which is around the corner from treatment 4 and 5, and has no color lines that run past its door) in the shot from the hallway. However, in the next shot from inside the treatment room, we can see they're not in treatment 7, but actually in treatment 4, note the red, green, and yellow lines on the hallway floor in front of its doorway, and treatment 7 has no lines that run past its doorway. When Dixie, Early, and Brackett step into the hallway it's even more obvious.
Audio problem: When the guys reach the top of the tower ride at Oceanland Park, we hear Captain Stanley say, "Kelly, you go up on top and throw the tag line over the side, we'll take the stokes up that way," but Cap's mouth is saying something entirely different.
Family Ties - S6-E16
Other mistake: Before the fire in the patient's room, which is caused by liquid shorting out the clock radio, we can see the tape covering the brand names of the baby powder and the clock radio.
Revealing mistake: On the way to the basketball game against 16, when all the guys are pushing Chet's station wagon down the street, it's Kevin Tighe's double who is pushing the car, and he looks nothing like Kevin.
Continuity mistake: During the basketball game against 16, when Chet is finally in The Game at halftime, 51's side of the court is at the right of the screen, but in the closeups of Chet's shot going into the hoop - scoring, we can tell by the wall and backboard that a bunch of his baskets are actually going into the hoop on the other side of the court, behind him.
Revealing mistake: When the woman from the car accident is in the ER, she goes into V-fib, so Brackett, Morton, Roy and Johnny work on her and defib four times without success, and as we hear the hum of the flatlining, the camera pans to the left just low enough so that we can see her lying on the gurney, with her blue shirt still buttoned up.
Continuity mistake: When the woman from the car accident is in the ER, and goes into V-fib, Brackett, Morton, Roy and Johnny work on her. Johnny does chest compressions and they defib three times, then Morton takes over the chest compressions, but when Brackett is about to defib the fourth time we see Johnny's arms stopping the compressions, when in fact it was Morton doing them at that time.
Paper Work - S6-E11
Other mistake: When the little boy is stuck in the storm drain with the rushing water from the broken hydrant, Johnny climbs into the manhole and is submerged up to his shoulders in water while dealing with the boy, but when they lift the boy out and lay him on the grass, Johnny is quite dry except for some wet patches on his shirt.
Captain Hook - S6-E8
Other mistake: When Roy and Johnny rescue the deputy from the wrecked chopper that sank in the water, they emerge from the water soaked from head to toe, but when they are pulled to the top of the cliff, Johnny and Roy are both completely dry except for a few small wet patches on their shirts.
Other mistake: When Johnny, Roy, and the cardiac patient are stuck in the stalled elevator with smoke in the shaft, Captain Stanley notifies dispatch that he wants a full first-alarm assignment, and we then see Engine 8 pulling out of their bay and heading to their run. The problem here is that this shot of Engine 8 is from the episode "Equipment" in season 5, when Johnny was doing overtime with Station 8, and we can actually see Johnny sitting on Engine 8 as it drives by.
Loose Ends - S6-E12
Other mistake: At the fire in the freight yard, Captain Stanley asks the dispatcher to respond a second-alarm assignment, and then we see Engine 8 pulling out of their apparatus bay and driving down the street. The problem is that this particular shot of Engine 8 is from season 5, episode "Equipment", when Johnny was doing some overtime at Station 8, and we can actually see Johnny sitting on Engine 8.
Loose Ends - S6-E12
Visible crew/equipment: When Dixie visits Brackett in his hospital room, he insists on seeing the little girl from the accident, but she convinces him to get back into bed. Then as he says "Alright, but later I want to see her," the actor's tape mark is visible on the floor near the second bed, where Dixie stands as Brackett gets back in bed.
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.
