Canadian heartthrob Justin Bieber has revealed that he plans to release a "special movie" around Christmas as long as it is finished in time.

His manager, Scooter Braun, took to Twitter earlier this afternoon (September 9) and told his 3 million followers that the 'Boyfriend' superstar is working on a film project along with new music and both should be unveiled before the end of the year.

Braun wrote: "And yes... @justinbieber gives u some new music in October until December and then a special movie on Christmas. ...provided we finish the movie on time @jonmchu."

Jon M. Chu, who worked on Bieber's 'Justin Bieber: Never Say Never 3D', shared a snapshot of himself with Bieber (pictured below) last night and explained that he has been showing him clips of the movie, titled 'Believe'. The film has just been privately screened at the Toronto Film Festival.
