Marvel and Lionsgate are preparing to release the latest in their line of Direct-to-DVD animated films with Next Avengers: Heroes of Tomorrow. The third trailer for the film has now been released over at and you can also watch it here. Check it out below

Marvel has provided the following summary of the film:

Whenever the forces of evil threatened mankind, Earth's mightiest heroes, the Avengers, were there to stop them - until they made the ultimate sacrifice in their final fight with the indestructible robot, Ultron.

But all was not lost, for Tony Stark (Iron Man) kept the children of the Avengers safe and raised them to become the teenage heroes of tomorrow.

Now James (son of Captain America and Black Widow), Torunn (daughter of Thor), Azari (son of the Black Panther), and Pym (son of Wasp and Giant Man) must finish the fight their parents started. Soon the arrow-slinging son of Hawkeye will join their ranks, but it will take more than five teens to destroy the machine that defeated their parents.

If these young heroes have any hope of winning, they must find the missing Hulk and come together as... the Next Avengers!

In addition to the new trailer, Marvel has provided another treat for the fans. The full movie will air on Friday July 25 at 8:30 p.m. at the 2008 San Diego Comic Con. Following the screeing there will be a panel including the film's Supervising Producer Craig Kyle, Producer/Supervising Director Gary Hartle, Writer Christopher Yost and some of the voice talent from the film.

Next Avengers: Heroes of Tomorrow hits DVD and Blu-Ray September 2, 2008.
