MUMBAI: An independent film on Sarah Palin is all set to release in June, much early before the battle for the 2012 election.

Titled Undefeated, the film is slated to premiere in late June in Iowa and then hit New Hampshire, South Carolina and Nevada before opening in 50-100 markets nationwide. The film will seek a PG-13 rating, although an unrated edition may contain some anti-Palin language and imagery.

The two-hour, Palin-sanctioned documentary feature directed by conservative filmmaker Stephen K. Bannon will release before the HBO‘s Palin-John McCain biopic.

Bannon, who acquired audio rights to Palin‘s bestseller, Going Rogue, uses passages from the book to narrate the film. The film also uses clips of Rosie O‘Donnell, Matt Damon, Bill Maher, David Letterman, Louis C.K. and Howard Stern, all trashing Palin, in the doc‘s opening moments.

It is said that Bannon came onto the project as after being approached by Palin‘s aide Rebecca Mansour. Originally intended as a series of videos, Bannon opted to craft a feature out of the material with a reported budget of $1 million.
