Well director Jon Favreau certainly is! Speaking during a mini press conference for the Iron Man DVD, Favreau introduced the thought of having a three dimensional Iron Man 2.
“… the highlight was Jon saying he’d love to do Iron Man 2 in 3D! He also called the IMAX Dark Knight footage a game changer and he said he’d love to shoot part of Iron Man 2 in IMAX. Regarding the 3D, he said it’s all about the cost, but if they can make it happen he’d like to do it. He talked about getting to see the armor in 3D and how cool it would be.”
Favreau also said that they are still in the writing process on the film and budgeting has yet to be discussed with Marvel (who will be paying for all of this rather expensive 3D goodness if Favreau gets his way). Should Iron Man 2 be in 3D or should that be kept for the Avatar‘s, Alice in Wonderland‘s and Ice Age 3‘s?
