25 Minutes of Significantly Less Goofy Avengers Blu-Ray Extras

Two extraordinarily lengthy “clips” from the upcoming “Building a Cinematic Universe” documentary on the upcoming Avengers Blu-ray have snuck onto the nerdformation supernerdway; together, they total over 25 minutes of what is supposedly a 90-minute doc (the second video is after the jump). I haven’t watched them yet, but the way Marvel has been taking down Avengers vids, I thought it was better for me to post them now rather than later. Enjoy! (Via Blastr)
