No big surprise here: the commercial success of Avatar paves the way for many more big-studio 3D titles. Warner Bros. Pictures today announced that Clash of the Titans will be released in 3D (and “2D”) worldwide on April 2. The studio plans 3D releases, including Harry Potter and Deathly Hallows, Part 1 (November), Cats & Dogs: The Revenge of Kitty Galore (July), Guardians of Ga’Hoole (September). Hey, nobody said they were all be any good.
