Continuity mistake: When Apollo is getting ready to fight the Russian boxer, he comes out with white boxing gloves on. Sometime during the announcement of the fighters, the camera shows Rocky and Apollo standing in Apollo's corner. Apollo is jumping up and down while pointing with an ungloved and untaped hand, He is saying "I want you". The next time they show Apollo, he has his gloves on again. (00:26:55)
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)
Revealing mistake: Take a good look at the lower right corner during the 'Hearts on Fire' training sequence at a barn in Russia. Rocky does a few leaning sit-ups; at that moment the cow in the lower right corner moves backwards. When you look closely you'll see it moves back too quickly and anatomically incorrectly, thus revealing it's a fake head attached to wheels or something. (00:57:45)
Continuity mistake: In the scene where Apollo is playing with his dog in his pool while hearing the news of Ivan Drago on television, he has three tennis balls in his hand. In one shot he throws 2 of the tennis balls to the dog, and in the next shot he is seen with 3 balls back in his hands while looking at the television.
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)
Continuity mistake: Before the final round, one of the Russian politicians slowly rises from his seat, comes down to the ring (from all the way up in the luxury suites) yells at the trainer, yells at Drago, then is picked up by Drago and thrown into the crowd. Then Drago says some things to him in Russian. In standard boxing, the period between a round is always 60 seconds. That Premier got down to the ring amazingly fast. (01:17:30)
Deliberate mistake: At the end of the second round when Rocky is holding Drago's arm and punching him, Drago snaps his head back for a punch that completely misses his head and lands on his shoulder.
Continuity mistake: When Rocky and his crew arrive in Russia, watch the Mercedes limo that picks them up. In the last shot at the airport as they are getting into the car, it has tinted windows in the back where in the previous views they were clear. This only happens once and the next view of the car when they drive up to the training farm shows the windows are clear and the passengers are visible.
Revealing mistake: As you watch Rocky fight the Russian, watch closely during round three. In a couple of punches, you can see that Drago does not make contact with Rocky, but the sound effects and Rocky's movements indicates that Drago hits him hard. (01:13:45)
Factual error: The limos they are driving in Russia are American Mercedes Benz models (American style bigger bumpers and headlights). Very unlikely at that time.
Continuity mistake: At the end of the second round between Rocky and Drago, Drago has both eyes cut when Rocky throws him to the ground, but he only has one eye cut when he gets to his corner.
Continuity mistake: Midway between the first and second round in the 'Creed vs. Drago' match the broadcaster states, "Ivan Drago is definitely for real." During his statement there is one camera angle peered on Drago's backside with no trainer within the proximity of his left side. Then immediately there is another camera angle peering on Drago's right side with a trainer placing his mouthpiece to the left in close proximity as the broadcaster finishes his statement. This suggests no discontinuity of time between the two camera angles as the trainer magically appears out of nowhere. (00:31:20)DavetheraveM
