Alternate versions

The "30th Anniversary Edition", released on video in 1997, features the original sound mix as it was originally intended. Because of this, some sound effects and fragments of dialogue previously nearly drowned out by music are now heard distinctly. There is even a section--the comically disastrous, very first meeting of Guenevere and Lancelot--in which offscreen court musicians are heard playing on mandolins, whereas previously this scene was acted without music.

The version shown on cable channels in the 1980s featured the Warner Bros-Seven Arts "W" logo in the opening credits instead of saying "Warner Bros-Seven Arts presents". All other releases of the film (including the original roadshow run, the film's general release, re-releases, the 30th anniversary VHS, and the DVD) are without the logo, and simply say "Warner Bros-Seven Arts presents". But oddly enough, the cover of the film soundtrack album says "Warner Bros. Pictures Presents", and shows the famous Warner Bros. shield.

The version shown in what were then known as neighborhood theatres (i.e., second run houses) was shorter than the full-length one by about a half hour, and the cuts were very obvious. The first cut occurred after Arthur said the line "He lives backwards" (referring to Merlin). In the cut version, he does not explain what it means, while in the full-length version he does. Also gone in the cut version were half of Lancelot's first song "C'est Moi", half of Guenevere's song "The Simple Joys of Maidenhood", Arthur's spoken monologue during "How To Handle A Woman", and the entire scene in which Arthur, in the forest, remembers the lessons that Merlin taught him as a boy. The film was subsequently re-released a year later with the tagline UNCUT!, although it turned out to be still cut in the same spots. It was not until its first telecast (in two parts on NBC) that all the cut moments were restored.

In the "30th Anniversary Edition" of the film, the opening credits fade out to a discordant, ominous musical note, as if anticipating something tragic about to happen. This is not the case on any other release of "Camelot", including the theatrical releases and the DVD, in which the orchestral rendition of the song "Camelot" (as heard during the opening credits), fades out softly and peacefully.
