*Anthony Mackie is in negotiations to join Ben Affleck and Justin Timberlake in the online gambling thriller “Runner Runner,” reports Variety.

Timberlake stars as a Princeton student who is cheated of his tuition money playing online poker. He flies to Costa Rica hoping to reclaim his losses from the site’s billionaire owner (Affleck) and ends up becoming the corrupt CEO’s right-hand man.

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.

The film is from 20th Century Fox, New Regency and Stone Village Pictures, says Variety. Brad Furman (“The Lincoln Lawyer”) directs from a script by “Rounders” scribes Brian Koppelman and David Levien.
