You may already have heard that an ESPN movie is in the works, based on “Those Guys Have All the Fun”, a book by Tom Shales and James Andrew Miller.

Last night (July 28) on Keith’s new Countdown on CurrentTV, Keith and his old friend and former sidekick Dan Patrick discussed who might play the various persons depicted in the book. It quickly became apparent that there is only one person who can ever be properly cast as Keith Olbermann; particularly a young Keith Olbermann: Ben Affleck.

Click on the picture below to see why. It’s a famous (notorious?) video clip of Affleck doing a spot-on satirical impersonation of the classic angry/indignant Keith, in 2008 on Saturday Night Live.

Below that, you can click and watch as Keith and Dan discuss their casting choices for the movie.
