Corrected entry: Before the start of the Cain-Gunn Heavyweight fight, we see promoter George Washington Duke announcing the fighters. He announces Union Cane's weight, but does not announce Tommy Gunn's weight. In any sanctioned boxing match, both fighters' weights (and even other statistics) are told to the audience.
Corrected entry: In the final fight scene, Rocky and Tommy Gunn crash through a fence and onto the street, where they fight under the elevated subway line (the Market-Frankford "El"). The fight occurred after Rocky took a walk to a neighborhood bar (where everyone knew him), which means that the bar should be/was located in South Philadelphia, where the El doesn't even run, and where the Broad Street Line (the other subway in Philadelphia) runs underground.
Corrected entry: In the scene where Rocky's son finally stands up to the bullies at his school (and gets his jacket back) the one kid initially says 'What's the matter Stallone, you not talkin' to me?', rather than Balboa. I watched the movie 'On Demand' and couldn't believe my ears, but I went back and it is what is said.
Corrected entry: During the scene on Christmas day right before Rocky's son, Robert, storms out the door- Rocky is explaining to him how important it is to be with one's family during the holidays. Rocky asks Robert if he remembers last year and all the fun they had. This film occurs immediately after "Rocky IV" (1986) and Rocky's bout with Drago. Therefore, "last year" Rocky was in Russia training to fight Drago for their Christmas Day boxing match. He spent most of the winter in Russia for training, so when did all this fun holiday activity happen that Robert is supposed to remember from "last year"?
Corrected entry: A major plot point in this film is that Rocky loses all his money, and is forced to move back to the lower-middle class neighborhood in which he used to live. Excuse me? We have here a good-looking, white, American, undisputed heavyweight champion, who gained immense popularity by fighting like a warrior and always remaining humble. (A sports rarity indeed). Yet apparently there were no endorsement deals to be had, and no card shows nearby, where Rocky could have made say $20,000 in a single afternoon of signing autographs.
Corrected entry: In Rocky V, Rocky tells his son that he was scared for all his 72 fights. But in the first Rocky he tells Adrian that he had fought 64 fights and never broke his nose. When you start counting, it is not correct. He fights Apollo in Rocky I and II, then in Rocky III he defends his title first 10 times, then he fight Clubber Lang 2 times, last he fights Drago in Rocky IV. So in Rocky V, he has fought 79 fights and not 72.
Corrected entry: You see in this movie a flashback of Rocky with his former coach Mickey. There you can see that he gives Rocky Marciano's cufflink to Rocky Balboa. And he wishes him good luck against Apollo. So that has happened around Rocky I or II. You never see him wear that cufflink in Rocky I, II, III or IV, but after he fights Drago in Rocky IV you see him in the shower with the cufflink on a necklace, that is very strange, because in the previous movies he never wore it.
