Continuity mistake: When they are discussing who Apollo should fight you see Apollo leaning towards the wall with his arm. In the next shot Apollo has his arm in his pocket. (00:28:40)
Continuity mistake: When Rocky closes the door there are three darts stuck to it. When he comes out there are only two darts. (01:05:15)
Revealing mistake: When Rocky wakes up on the day of his first jog, the radio announcer reports that it's 28 degrees outside. However, when we see Rocky jogging, you can't see his breath. (01:07:45 - 01:09:00)
Continuity mistake: When Rocky goes to see Pauly at the meat market, Pauly places a steak in a wrapper and puts a small piece of tape on it. When Rocky leaves after hitting the hanging meat you can see that the piece of tape on the wrapper is much larger than before. (01:13:00 - 01:13:50)
Revealing mistake: Rocky says "cut my eye" during the fight scene, if you watch closly you can see the man actually squeeze a tube full of red stuff inches away from his eye. It's really quite funny... (01:49:20)
Visible crew/equipment: During the final fight, a steady cam operator with a white shirt and black straps around his body is seen during several wide angles. This is not a TV camera, it is a film crewmember. The Director even admits to it in the audio commentary on the DVD.
Other mistake: About half way through the movie, Adrian gives Rocky a dog (Butkus). The second time Rocky goes to the meatpacking plant, the dog is with him when he walks in, but he walks out alone and the dog is not seen again in this movie.
Suggested correction: How is this a mistake? Rocky could easily have left with the dog on another occasion. It's like saying, sometimes Rocky is shown in a location but it's never shown how he got there. That isn't a mistake, it's just what happens in films. Also, the dog not being seen again is irrelevant.
Continuity mistake: When a particularly unfit Rocky runs up the steps at dawn, when he reaches the top and we go to a different shot, it's a lot lighter. When returning to the previous angle, it gets darker again.
Revealing mistake: At the end of the movie when Adrian is climbing into the ring, Rocky turns to her and for a very short time you can see the line between the make-up appliance used on his right eye to make him look beat up and the skin of his right cheekbone as well.
Continuity mistake: In the last fight, several punches are used twice, shot from different angles.
Continuity mistake: There is a dartboard in Rocky's apartment. During a touching scene between Adrian and Rocky, you can see the darts on that board change position/number between shots. No one is playing darts at the time.
Continuity mistake: In the last fight scene, particularly during the close-ups of the fighters, you can clearly see in numerous shots that the auditorium seats are empty. This is contrasted with the earlier shots where it is jam packed as the fighters are entering the ring.
Continuity mistake: In the scene where Adrian is waiting for Rocky as he is returning home, she is going to surprise him with a gift, Butkus the dog. Rocky is standing about 25 feet from her so he has a good angle to see the entire porch. When she presents him with the dog, he acts surprised like he didn't see him on the side of the cement porch. Plus she is holding the dog leash in her hand. Rocky would have seen the dog immediately.
Visible crew/equipment: As Rocky is talking to Mickey in the locker room after his locker has been taken over by another boxer, you can see the shadow of the boom mic on the locker behind him as it dips in and out of view. As he starts walking away, you can also see it as it follows him.
Factual error: In more than one scene you can hear the sounds of a steam locomotive chugging and blowing the whistle. Steam locos were almost entirely phased out by the early 60's, and none ran in Philadelphia at the time this movie was made.
Continuity mistake: Tony, Apollo's trainer, gets into the ring twice at the end of the last match.
Audio problem: At the end of the fight when Apollo tells Rocky there won't be a rematch, his lips aren't moving. Rocky's lips aren't moving either when he says "Don't want one!"
Continuity mistake: In the scene where Mickey goes to Rocky's apartment to offer his services as manager, Mickey climbs the stairs and walks up to Rocky's door. The apartment number is on the outside of the door. The scene cuts to Rocky opening the door from inside the apartment. There is no longer an apartment number on the door. This happens before the bathroom door shot.
Suggested correction: This is not an error, the door that Rocky opens in that scene is the bathroom door inside of the apartment, not the front door to the apartment.
The continuity error mentioned above is true. This happens before the bathroom door scene. When Mickey knocks on his door there is a number 2 there. Then 5 seconds later when you see that same front door it has no number on it.
Revealing mistake: During the fight, it appears that the filming is done in FF to make it more dramatic. If you look at the movement of the crowd, it seems to be sped up. Still, masterfully done on a low budget.
Audio problem: When Rocky is in the locker room with Spider after the first fight, Spider supposedly says (according to subtitles and closed captioning), "Hey. You really got lucky," but that's an obvious post-production overdub. His lips are saying "sometimes".
Suggested correction: As pointed out several times before, breath showing in the air is about humidity, not temperature. See Alien vs Predator for similar corrections.
This is a misunderstanding about how humidity plays a role in seeing your breath. If the relative humidity of both your breath and air outside combined is 100%, you'll see your breath, this means you can see your breath at higher temperatures. To reach 100% relative humidity, the outside humidity needs to be higher or the temperature needs to be lower. However, at a certain temperature (usually around 45°F), you'll always see your breath. So at 28°, you'll always see your breath, no matter what the humidity is. This is a valid revealing mistake.
