In the upcoming 3D animated movie ‘Megamind,’ Will Ferrell voices the mega-villain Megamind, who kills his main superhero nemesis — and therefore decides to create a new, even better one. Complications, as you can well imagine, ensue. Dreamworks’ Phil McNally, an animation supervisor who’s such a 3D expert, he’s known as “Captain 3D.” (Yes — that’s his actual nickname.) Captain 3D describes some of the new technology used for ‘Megamind,’ and we get several tantalizing glimpses at the movie as it’s being made. As for the future of 3D technology itself, Captain 3D tells us, “It’s really here to stay this time.” We’re starting to believe it.
