Deliberate mistake: While Donnie is training at Front Street Gym, when Rocky repeats, "One step at a time, one punch at a time, one round at a time," the closeup of two children watching from outside the ring is a flipped shot, note the backwards Nike swoosh logo and Everlast ring rope spacer.

Factual error: When Creed and his girl go to the sandwich shop the cashier tells him it's $10.95. He hands her a $20 and she gives him back a $10 bill. Not only that, there is no way you would get two fully loaded Philly sandwiches and drinks for $10.95 in Philly.
