Will there be a chance for an Iron Man 2, as The Avengers will be the sequel to IM, Hulk, Captain America and Thor all rolled into one?
It'll be a shame if there isn't as there's a lot more can be done with this character and his storylines.
The Mandarin would be a great choice for the villain in IM2, with his alien rings.
Also, as IM is technology based, obvious enemies can be tech base as well, like Iron Monger was in the origin film.
IM has the potential to be a great spy movie - Tom Clancy, James Bond, and Robocop all thrown in the mix.
