This is Richard Donner's 'director's cut' version with about eight minutes of additional footage edited in, which nearly doubles Marlon Brando's screen time. The 3-disc set also contains 'Superman II' and DVD-ROM features include making-of featurette, screen tests, deleted scenes, audio outtakes (DVD-ROM feature run time: 56 mins. approx., these features can be viewed/listened on PCs with DVD-ROM drives, but it's not Macintosh compatible.)
