Movie Theaters Unprepared for Onslaught of 3D Movies

But a limited number of theaters can show these movies in 3-D, because not all theater owners have bought new digital projectors and undertaken other upgrades necessary to show movies in the format. About 3,900 to 4,000 3-D-ready screens are expected to be available in the U.S. and Canada by the end of March. Typically a movie in wide release might be shown on 3,000 to 10,000 screens in North America.
