Marvel has released a trailer for Avengers Assemble, a new animated series that will receive a one-hour preview on Sunday, May 26th at 11am on the Disney XD channel, before it settles into its regularly scheduled time slot on Sunday July 7th (see "'Avengers Assemble' in July").
 
The new Avengers Assemble series, which replaces Avengers: Earth’s Mightiest Heroes, features a cast that closely mirrors that of Joss Whedon’s box office record-setting movie The Avengers: Iron Man, Thor, Captain America, Hulk, Hawkeye, Black Widow, and Falcon.
