A two-minute trailer for 'Things Fall Apart' -- the movie rapper 50 Cent shed a reported 54 lbs for -- has surfaced on the Internet. 50's film had its world premiere over the weekend at the Miami International Film Festival, where a reporter for the Examiner claimed "the crowd loved his movie."

In the flick, written by 50 and loosely based on the life of his childhood best friend, the rapper-turned-actor goes from a dread-locked NFL hopeful to an emaciated cancer victim. Already pegged the "most critically acclaimed role of 50's career," the film also stars Ray Liotta and is directed by Mario Van Peebles.

Watch the unofficial preview for the film after the jump. But don't expect to hear a 50 Cent song playing in the background. The sneak peek features Nelly's 'Just a Dream.'
