If you thought that you'd have to wait until next month's DVD and Blu-ray release of The Avengers movie to see the bonus features, think again. Almost half an hour of a documentary about the creation of Marvel's cinematic universe has been released online, giving you a sneak peak behind-the-scenes of the movie event of the summer.The two clips come from Building A Cinematic Universe, a feature-length doc that traces the creation of the Marvel Studios movies all the way through this summer's Avengers, including interviews with Joss Whedon, Marvel Studios president Kevin Feige and the stars of Avengers, Iron Man, Thor and Captain America: The First Avenger (as well as, of course, Stan Lee).

The original incarnations of the video from Comic Book Movie are no longer online, but you can watch these uploads -- courtesy of Blastr -- for now.

Marvel's The Avengers is released on Blu-ray and DVD on September 25.
