The Avengers: Earth’s Mightiest Heroes – Prelude

A 110 minute prelude to the 2010 animated series, consisting of five-and-a-half-minute chapters created from footage from season-one episodes, premiered online and on Disney XD on September 22, 2010. Series supervising producer Josh Fine said the goal was to “let us explore the individual members of the team in their own ongoing adventures … do a lot of character development and set the stage for the rest of the season”.
