Traitor (2008)

"Co-written by Steve Martin" got me into the theatre but there was not a laugh in it and I found it more than a bit confusing (if only it had Burn After Reading's David Rasche & JK Simmons deconstructing the goings-on). It picked up in the second half, though, and Don Cheadle's performance was spot-on, especially after certain plot twists were revealed. Cheadle fans should see it for sure.
