Ben Affleck will not be playing the role of Tom Buchanan in The Great Gatsby because the Australian (damn you, Baz!) shooting schedule conflicts with his direction of a historical drama based on the 1979 Iran hostage crisis. It would appear that Argo takes precedence over Gatsby, so Baz Luhrmann and Co. will have to keep up the casting saga that is this film.

Gatsby still has Leo DiCaprio, Tobey Maguire, and Carey Mulligan commited, and Isla Fisher is in talks to play Tom Buchanan's mistress, Myrtle, so they're not hurting for star power, but I was actually really looking forward to Ben Affleck hamming it up as an upscale jerk, a type that we haven't seen him in since he was cast as the proprietor of Fashionable Male way back in Mallrats.

I feel really sorry for the casting director of The Great Gatsby. Where are you supposed to find a rich asshole in Hollywood on short notice? (Deadline)
