Few years ago, Marvel produced this short film in three parts different parts. Above video contains all the parts of Spider Man, Iron Man and The Hulk animated short film.
It was made as commercial for the Marvel Comics.
I think many of you already have seen this animated short film of Spider Man, Iron Man and The Hulk!
I would totally love to see CG animated film of The Avengers like this rather than live action.
Even if this video has been made few years ago the character animation quality is really good and way more better than the crappy CG animated series Iroman Armoured Adventures.
I can tell that Neil Patrick Harris has given voice for the Spider-Man and would love to know who voiced Tony Stark in this animated short.
You can also see that how Joss Whedon had borrowed one scene from this animated short into The Avengers live action movie.
