Sorry to break this to comic book movie fans, but it's the truth: Marvel's The Avengers was a once-in-a-lifetime event. Skeptics expected it to be a giant clusterfuck, while optimistic folks kept their fingers crossed in hopes that writer-director Joss Whedon could really nail one of the biggest superhero movies of all time. In the end, a domestic gross of $623 million (on an already whopping $220 million budget), endless merchandising, and outstanding reviews from critics proved the naysayers wrong.

Celebrate Whedon's massive achievement with this jam-packed home video set, featuring extended scenes, an alternate opening and ending, a gag reel, and the exclusive short film Marvel One-Shot: Item 47 (starring Lizzy Caplan).
