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)
Visible crew/equipment: The last scene, between Rocky and Apollo is full of visible crew/equipment. First, when they're talking, you can see in the left-bottom corner of the screen a shadow moving. When Rocky and Apollo are talking before they fight, you can see on the ground the shadow of the cameraman. And when they start walking in circles and the camera moves with them in circles, you can see a crew member that watches them talk.
Visible crew/equipment: At the end of the movie during the rematch, a movie camera can be seen filming during several shots of the fight. This is a film camera and not the video type used for news or TV broadcast. Also, it's the only one seen at ringside and the cameraman has an assistant following him the entire time.
Visible crew/equipment: During the second fight, there's a brief shot looking at the opposite side of the ring. A large motion picture camera and its operator are blatantly visible in the crowd.
Answer: Clubber Lang worked his way up the professional ranks. If you notice, the challanger is still able to fight, the referee uses his own discresion to ignore the final punch as the match would have been called in Langs favour anyway.
