Visible crew/equipment: Just before the second fight with Clubber and just after the pre-fight brawl, when the camera switches to the shot of Rocky and Apollo you can see a director's chair at the top left of the screen with "Mr. T" written on it. (01:22:50)
Continuity mistake: As Garp is being placed aboard the helicopter, the rotor motor can be heard spinning, but there is no downdraft affecting the people in the scene.
Continuity mistake: When Kenny Rogers gets trapped in the rest room at the beginning of the film, he pulls the knob out from the door. When this happens, the knob is on the left side of the door from his point of view. After he climbs out the window, the door has changed to having the hinges on that side and the style of the door does not look like it has a knob at all. A rest room this size would only have one door, so it has to be the same door.
Revealing mistake: The actors all have the speed, form, and physique of high school athletes- not people headed to the Olympics.
