"Justin really wants to break into movies but he wants to do a project of his own. He loves action movies and is a huge fan of Mark and sees him as very much the kind of actor he wants to be - especially as Mark started out in pop," showbizspy.com quoted a source as saying.
"Unfortunately, Justin hasn't quite got the physique for an action movie just yet. He's working out with a personal trainer but the fitter he gets, the skinnier he ends up," the source added.
