Directed by Jon Chu (who also directed Bieber in his 2011 film, "Never Say Never"), the film will include concert footage as well as a behind-the-scenes look at Bieber's life.
"I am so excited to be involved in this movie, and so happy to be able to give back to my fans, especially during the holiday season," Bieber said. "Jon Chu and my team have done a wonderful job creating a special moment for Beliebers worldwide and I can't wait till Christmas day when the movie will be in theaters everywhere."
In addition to his moustache, the movie will also include interviews with Bieber and his inner circle, including manager Scooter Braun, mentor Usher Raymond, Rodney Jerkins, Ludacris and Mike Posner, among others.
"It's no secret that Justin Bieber's name drives a lot of attention," Braun said in a statement. "But with 'Believe,' we wanted him to tell his own story, truthfully and directly. The number one goal of our company is to provide global audiences with content that's not only high-quality and forward-thinking, but also authentic."
Bieber, Braun, Usher, Bill O'Dowd, and Garrett Grant all serve as producers. Along with Open Road Films, the movie will be released by SB Films and Dolphin Films.
Leading up to the movie premiere, the 19-year-old singer has been dropping new tunes during his 10-week Music Mondays series. So far, he's given fans two tracks, "Heartbreaker" as well as "All That Matters."
