Avengers Assemble!
... a made-for-DVD animated film.
It looks to be about on the level of the GI Joe vs. Serpentor film from a while back, you know the one where Don Johnson's shotgun fired laser beams.
Oh man, it looks like they're playing Giant-Man for laughs, too. Whee! Guess he's not gonna get into a fight with the Wasp in this one.
