Ben Affleck's third outing as director is Argo a bit of a Hollywood farce, a bit of a political drama and incidentally based on a true story.
His debut, Gone Baby Gone was a good story well told that deserved to be seen more. His sophomore effort, The Town, was a smart mix of action, drama & interesting characters that almost made it to the Oscar race. The 70s setting of Argo should fit his unfussy, thoughtful storytelling well, and means that, at the very least, there will cool suits and cool beards.
On another note, John Goodman seems to be cornering the market for playing period Hollywood film producers.
