Gemma Arterton has joined the online gambling thriller "Runner, Runner" says Variety.
In the film Justin Timberlake stars as a Princeton University student who gets pulled into the world of online gambling in order to help bankroll his expensive education. After he loses money he flies to Costa Rica hoping to reclaim his losses from the site's billionaire owner (Ben Affleck) and ends up becoming the corrupt CEO's right-hand man.
Gemma will play JT's love interest
Anthony Mackie is in talks to play an FBI agent who has spent years trying to bring down Affleck's character and sees Timberlake as a way in. Project X co-star Oliver Cooper will play an Ivy League computer nerd who gets hired along with Timberlake's character.
Brad Furman ("The Lincoln Lawyer") will direct from a script by "Rounders" scribes Brian Koppelman and David Levien.
Koppelman, Levien, Leonardo DiCaprio, Jennifer Davisson Killoran, Michael Shamberg, Stacey Sher and Scott Steindorff will produce the pic.
Shooting begins next month in Puerto Rico.
