One of the best parts of NBC's "The Office" arriving on Blu-ray on Sept. 3 is the fact that it will contain audition tapes as a bonus feature.

The never-before-seen footage contains now big-time actors such as Seth Rogen auditioning for the hit NBC comedy in 2003 during a three month casting process.

• Judd Apatow prodigy Seth Rogen for quirky "Dwight Schrute," went to Rainn Wilson.
• "Modern Family" star Eric Stonestreet for lazy "Kevin Malone," went to Brian Baumgartner.
• "Breaking Bad" actor Bob Odenkirk for boss "Michael Scott," went to Steve Carrell.
