It’s a 3-D world, and Jeffrey Katzenberg thinks it’s time to reflect that on the big screen — and not just in animated films. “In five to seven years, all films, regardless of budgets or type, will be made in 3-D,” the DreamWorks Animation boss said Wednesday during his keynote at the inaugural 3DX Film and Entertainment Technology Festival. “3-D is how we see, how we take things in. It’s natural,” Katzenberg said. “This is not a gimmick, it’s an opportunity to immerse the audience, to heighten the experience.” He added that the migration to 3-D will happen on all screens, including mobile phones and laptops.
