Next Avengers: Heroes of Tomorrow

Next Avengers: Heroes of Tomorrow (originally titled Young Avengers and also known as simply Next Avengers) is a 2008 American animated superhero film that is a spin-off of the two Ultimate Avengers films. By the release of its first look preview in August 2007, the title had changed to Next Avengers instead of Young Avengers. Fred Tatasciore repeats as the Hulk from the Ultimate Avengers movies.

With the loss of their Avengers parents at the hands of Ultron and raised by billionaire bachelor Tony Stark/Iron Man, four orphaned teens, James Rogers (son of Captain America and Black Widow), Torunn (daughter of Thor and Sif), Henry Pym Jr. (son of Giant Man and Wasp), and Azari (son of Black Panther and Storm), must live up to their parents' legacy and defeat Ultron, the mechanical and maniacal foe that defeated them. Additional allies are recruited including Vision, the Hulk and Francis Barton (son of Hawkeye and Mockingbird).

Released theatrically on September 5, 2008, the film received mixed reviews from critics, who praised the animation but criticized the campy tone of the film. Despite grossing $49 million on a budget of $10 million, it was viewed as a box office disappointment by Marvel, and the Ultimate Avengers did not receive any more installments.

Box office
In the United States and Canada, the film opened alongside Bangkok Dangerous and was projected to gross $6-10 million in its opening weekend. The film grossed $4 million on its first day, including $210,000 from Thursday night previews, and debuted with $10 million, making it the only film in the Ultimate Avengers series to top the box office at all. In its second weekend, the film grossed $5 million, falling to fifth, and in its third weekend, the film grossed $3 million, ranking ninth. The film closed out its domestic run with $21 million, which Marvel executives called "well below our expectations", saying "we really thought it could end up with $30 million domestically, since this is a more kids-oriented film".
