Japan unspooled “Chicken Little” on Thursday, Japan’s first screening using the Disney Digital 3-D system, at the AMC Ikspiari multiplex in the Tokyo Disney Resort.The screening introduced the media to the system before sneak previews at the weekend. The film opens nationwide this Friday. The 16-screen plex is the first in Japan to install the system, even if it’s on only one screen. The Warner Mycal Cinemas site in Tama Center, a Tokyo suburb, will also screen the film using the Disney Digital 3-D system after the start of its wide release. The system is already in use at 84 sites in the U.S.
