Character mistake: When Rocky makes his speech after his fight with Drago, he says that it's better that one person fights another instead of a million fighting a million (a US USSR war). The Russian translator misinterprets his speech and says that this is better than a million dollars. You don't have to understand Russian (although I do) to hear the translator says million dollars to confirm this blunder of a mistake. (01:22:25)
Rocky IV (1985)
1 character mistake - chronological order
Directed by: Sylvester Stallone
Starring: Sylvester Stallone, Dolph Lundgren, Burt Young, Carl Weathers, Brigitte Nielsen, Talia Shire
Continuity mistake: When Apollo is knocked out during the fight with Drago, he falls to the canvas in slow motion. During the fall his hands are hanging down, but in the next shot, when he lies on the floor after the fall, his hands are in front of his head. In the next shot his arms are down again. (00:31:25)
Rocky: Going in one more round when you don't think you can - that's what makes all the difference in your life.
Trivia: Sylvester Stallone, actually tore a muscle in his heart while filming the training sequence in which he lifts the sleigh that everybody was sitting in. Filming had to stop for two months so doctors could make sure that he healed properly and the chances for him having a heart attack would be reduced.
Question: Why and who were the guys following Rocky in the car when he was training?
Chosen answer: People who worked for the Soviet government assigned to spy on Rocky.
Answer: They were Rocky's chaperones. They were even seen in the cabin Rocky was staying in and playing chess with Duke.
