I bought this four pack DVD box set since I'm a die hard Superman fan. Yes, it saddens me that the last two films in the series aren't as good as the first two movies. The original film, though, was of course the one given the DVD Special Edition treatment.
There's a lot of extra stuff on the Superman: The Movie Expanded Edition. Here they are: audio commentary by director Richard Donner and creative consultant Tom Mankiewicz, soundtrack remastered in Dolby Digital 5.1, music-only audio track, three behind-the-scenes documentaries with the cast & crew, deleted scenes, screen tests for Lois Lane, Ursa, and Superman, audio outtakes, two theatrical trailers, TV spot
This is really one of the best DVDs that I have ever seen released. Truly stuff that movie fans want to see. I'm truly thrilled that one of the best films ever made got the DVD magic. For that alone, given the extra treatment that Superman: The Movie got, I rate this box set 5 stars!
Also, get a copy of the 2 disc Superman: The Movie remastered soundtrack released by Rhino Records. This soundtrack includes previously unreleased material by composer John Williams, and who can't say that Williams' Superman theme is one of the best themes ever composed?
As for the three Superman sequels, they all got their trailers as the bonus, and widescreen treatment. Sure, it's great to see them all in widescreen to see the maximum view of footage, but still I wish they got some extra bonuses of some kind.
Superman II is a great sequel, but I wish something was done to see more of Richard Donner's footage as an extra bonus. Superman III is an awful film to watch (too much Richard Pryor and the silly campiness). Superman IV is actually more watchable in my opinion than part III, although it too is not great of a film, but I did like the nuclear disarmament theme used as the film's story plot (and it was great to see it in widescreen since I saw this film in the theaters back then).
Of all the sequels I wished got some extra DVD treatment, I think the last film in the series, Superman IV: The Quest For Peace should have gotten it. The film has been available for all its existence as a 90 minute confusion, when actually there was an original 134 minute cut of the film shown in a test screening in early 1987. This version would have revealed there was an earlier Nuclear Man that Lex Luthor created, and more would have been revealed with Mariel Hemingway's character, and other loose plots that the 90 minute version failed to hide away. Superman IV may be the shortest film in the series, but I think Warner Bros. should have given it the Special Edition treatment on DVD as a true bonus for the general public to know, and for Superman fans to finally see.
Rumors are that Superman IV's 134 minute cut has been destroyed, but I hope that isn't true. Maybe one day we will get to see it.
