Behind the Scenes of "How To Be"

How to Be will be released on a U.S. tour of film festivals beginning April 10 in Las Vegas.

In the film, Rob plays a depressed London musician who moves back home to fix his seemingly useless life after stumbling upon a self-help book called It’s Not Your Fault.

The 22-year-old actor looks dramatically different than the sex icon we know and love, sporting a long, shaggy 'do, disheveled clothing, and lacking all the self-confidence we saw from his character in Twilight. Check out the behind-the-scenes footage from the flick:
