- The film writer Bob Gale revealed in an interview that the character Biff Tannen from Back to the Future Part II was based on Donald Trump. - In the movie, Biff lives in a penthouse above a casino, similar to Trump's Plaza Hotel in New York. - Both characters share similarities like their signature hairstyles and multiple marriages. - The only thing the writers got wrong was not having Biff use Trump's signature insult of "loser" instead of calling people "buttheads".
