While it might be interesting to see Guy Pearce and Don Cheadle run around in an espionage thriller without any other characters, that isn't very realistic. Variety is reporting that more have been added to the cast of Traitor -- the big names being Jeff Daniels and Neal McDonough. The former is coming off some higher-cred films like Infamous and The Lookout, and recently completed a role in Mama's Boy -- the slacker romcom with Diane Keaton and Jon Heder. The latter was last seen in LiLo's latest flop -- I Know Who Killed Me, but also flicks like Flags of Our Fathers. (This also reunites McDonough with Pearce -- both were in Antonia Bird's Ravenous.)

As for the rest of the names added to the cast -- there's Archie Panjabi (A Mighty Heart), Aly Kahn (Osama) and Said Taghmaoui (Hidalgo). While it would be nice to see these actors as fellow CIA or FBI agents, methinks you can guess what sort of roles they are getting. If you're foggy on the plot -- Steve Martin (yes, that one) came up with an idea that Jeffrey Nachmanoff has since written and will direct -- a CIA operative (Cheadle) is undercover in a terrorist group and becomes a terror suspect. Pearce plays an FBI agent who investigates terrorist activities. You can imagine where things go from there. The feature will head into production this Monday as TIFF zooms into high gear.
