If Marvel is going to do 3D, they want to do 3D right. "The team has been doing a lot of research into 3-D processes, and we're looking at it on future films when we have the time," Feige said. "We will be doing it at some point." That point may be Thor (which wasn't shot on 3D cameras and would have to be converted in post), but it's far more likely to be The First Avenger: Captain America. That begins shooting this summer in England, giving them ample time to use 3D cameras and all kinds of technological wizardry. It would also be a pretty ideal character to debut 3D with -- Cap is, after all, known for throwing that indestructible shield of his. He also slams people around a lot. It's the ideal prop for 3D, moreso than Mjolnir. (That's my humble opinion, of course.)
Of course, to those who really don't care for 3D, this will come as a bitter disappointment. If there's one thing the Marvel Universe might not need, it's more bells and whistles. Then again, the possibility of seeing Iron Man do 3D pelvic thrusts is an awfully tempting one.
