Plot hole: The events of Rocky V take place immediately after the conclusion of Rocky IV. With that being said, Paulie is being blamed for signing over the family's fortune to their crooked account. But how could that have been possible when the entire family, except for their son, was in Russia training Rocky for the fight with Drago?
Suggested correction: Because Paulie had signed over power of attorney to the accountant six years prior, the accountant had squandered the money and failed to pay Rocky's taxes all that time. It wasn't something Paulie was supposed to have done while he was in Russia.
That still would not have been correct, and the studios messed up on that particular part because 6 years prior to Rocky IV in 1985, the events of 1979's Rocky II happened. In this film, Rocky was broke and in desperate need of money. He had blown all of the money from his first fight with Apollo, lost his job at the meat slaughterhouse, and was broke. So tell me, during that time, how could Paulie have signed anything over to anyone? Rocky did not have millions at that time.
While Rocky II came out in 1979, it was set in 1976 - 10 months after the fight with Apollo.
Plot hole: Paulie couldn't be that stupid so as to not tell Rocky that his accountant needed his signature for a tax extension.
Suggested correction: Paulie isn't exactly a Rhodes Scholar. I doubt he has any formal education beyond high school. He likely has no knowledge whatsoever about what a power of attorney is or what it does. Very easy to trick.
And furthermore, Paulie couldn't have had anyone sign anything on Rocky's behalf. Once it's proven in court that someone forged Rocky's signature, then everything would have been reversed and he would have never lost his fortune. If this was that easy, then anyone could walk into an office claiming to know a billionaire, sign a piece of paper, and get all their money.
