As for the 50GB dual-layer disc, Feingold said both movies have long running times as well as hours of bonus features that the studio has produced but been unable to release on DVD because they take up too much space.
Sony also will take advantage of the enormous additional capacity to use uncompressed audio on some of its Blu-ray Disc titles, including two Sony/MGM titles in the first wave--The Fifth Element and The Last Waltz. Sony execs say that even movie theaters do not offer uncompressed digital audio.
