Alex Pettyfer (I Am Number Four) and Matt Bomer (White Collar) have joined the cast of Andrew Niccol's upcoming sci-fi flick Now (previously titled "I'm.Mortal").  The film takes place in a society where aging can be stopped so trading years in life becomes the predominant currency.  Deadline doesn't have any details on the characters Pettyfer and Bomer will play, but does note that they're starring roles.

The plot centers on "Will (Justin Timberlake) is one of those poor people, and tries to help his ailing mother (Olivia Wilde). When he is accused of murdering a rich man for his time, he goes on the run with a hostage (Amanda Seyfried) in tow."  The film also stars Cillian Murphy and Vincent Kartheister.  Click here to see photos from the set of the film.
