Revealing mistake: When Station 51 is dispatched to a man trapped at World Picture Corp, just as they reach the entrance to World Picture Corp, the Sheraton-Universal is seen on the corner, and the street sign for touring Universal Studios is visible as well. (00:19:45)
Revealing mistake: At World Picture Corp, when John and the guy with the broken clavicle are lowered from the overhead joists they're both wearing lifebelts buckled around their waists. The problem is that once they reach the ground, we can see the additional carabiner attached to John's lifebelt, which is also attached to extra green support protruding from under John's shirt. We can also see the victim's additional carabiner going under his flannel shirt. While Roy is on the line with Rampart, when John removes the victim's lifebelt, the extra carabiner is still protruding from under the victim's shirt and John places his hand over it. (00:27:00)
Revealing mistake: When Station 51 is dispatched to the gas explosion at the cafeteria, during the actual rescue the four firemen we see in closeup in the cafeteria are supposed to be Roy, Johnny, Chet, and Marco, but it's really odd that all are the doubles, very obvious in the closeups. There's little dialogue during this scene, which was dubbed later in ADR.
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.
