It's hard to imagine anyone other than Steve Carrell, or Rainn Wilson as their characters in 'The Office'. That is, until you see Seth Rogen auditioning for Dwight K. Schrute. Or imagine Bob Odenkirk (Saul from Breaking Bad) as Michael Scott.

That's what this unseen, until now, audition reel reveals. Over 3 months in 2003, producers for the show saw hundreds of big name actors audition for the coveted roles of the the main characters. Most of us had never seen the British version of the show at the time, but it's clear that the actors in this reel had. If you ask me, Eric Stonestreet  nails Kevin. But thank God he wasn't cast, because we would never have had his amazing performances as Cam in Modern Family.
