Comic book fans no longer have to imagine what it might be like to see all their favourite superheroes in one place after the cast for the upcoming Avengers movie was revealed.

Fans got the chance to meet The Avengers cast at Comic-Con in San Diego, when Samuel L Jackson surprised some 6,000 people gathered for a Marvel Studios presentation.

Jackson stepped on stage just as the presentation was ending and started introducing the cast of The Avengers. He brought out stars Clark Gregg, Scarlett Johansson, Chris Hemsworth of Thor and Chris Evans of Captain America.

He then introduced another surprise guest, Robert Downey Jr, who brought out the rest of the all-star cast, including Jeremy Renner as Hawkeye and Mark Ruffalo as Bruce Banner.

The Avengers is based on the comic book series of the same name, which brings various Marvel superheroes together. The film is due in 2012.
