According to the story:
There is a 1 minute demo of Iron Man 2 converted to high quality digital 3D. I'm told this one minute is totally like Kim Basinger & Mickey Rourke in 9 1/2 Weeks. HOT! Crazy Hot! Right now the Suits at Marvel & Paramount & now also Disney are considering this 1 minute.
Apparently, Marvel and Universal are taking bids from three separate companies to compare the costs of doing this. Should the numbers make financial sense, it seems that there is even talk of converting the original Iron Man to 3D.
