The film premiered Thursday night, giving Washington, D.C. a taste of Hollywood.
"Game Change" portrays John McCain and Palin's run for the White House. The film, which is set to debut on HBO Saturday night, is based on the bestselling book chronicling the 2008 presidential race.
"I think this campaign was notorious for being a difficult one and one that was pretty disorganized, I think anyone will tell you who was involved in the campaign. That to me was a real surprise," Moore said.
Both McCain and Palin have lashed out against the film, saying it is not an accurate portrayal of the campaign. Palin even released her own version of the movie's trailer as a response to the film.
However, the filmmakers insist the film is a fair representation of the events.
