We thought he'd be PERFECT for the part, which is why we're disappointed to announce that he won't be joining the film.
Due to scheduling conflicts with Affleck's upcoming directorial effort, Argo, it won't be possible for him to do both films.
A new Buchanan hasn't been chosen yet, but it looks like Luhrmann might recruit Australian actors for some roles, so perhaps Affleck will be replaced with an actor from the land down under.
We just hope they make a good choice. Ben Affleck would have definitely been a great fit for that role…
Who do U think would make a good Tom Buchanan?
