I'll wait to get into this more when I actually see it, but Affleck was initially attached to this and I think he would have been a better fit for this material. I read about a third of the script and it never really felt like the overly stylized movie like the trailers suggest it is. I interpreted it as being very assured and direct.
I have no beef with Fleischer. Zombieland was smart and very entertaining, and while 30 Minutes or Less wasn't very good, it had its moments. I just don't think he had the cred yet for a project like this. I'm glad Affleck chose Argo in the end though.
