I have not done a scene by scene comparison, but just looking at it quickly. the original B&W/Color version of The Cage and the restored full color show very little differences. The DVD release has the original in 29.790 fps and the restored version in 23.976 fps. In places the hybrid runs faster and in others the restored runs faster. There are also noticeable frame drops in the hybrid during the B&W sequences.
I am actually working on a “re-creation” of the full length Cage and there are many short omissions. The first step was to merge the Blu-ray version (the shortest of the official releases) with the hybrid version (the longest of the official releases), so now I have my own “hybrid” B&W/color version, which is actually longer than the 1986 version. The second step was to correct the speed of my 16mm audio, and try to sync it with the video, that’s when I noticed that even my “hybrid” version is too short, there are many segments were there is no dialogue just music and/or sound effects, and there is no footage for those parts available right now. Bits of dialogue are missing too, “you were like a wild little animal” is included in the 1986 and 1988 versions but dropped later, but lines like “probing you, searching for weaknesses” or “you wanna gamble we won’t” (hope I got it correctly) are in no officially releases versions. The dramatic reaction turn of Pike reacting to “soon we can start with the experiment” is missing the music which was included in The Menagerie and all home video releases, when Vina and Keylar (or whatever the spelling is) are fighting on the top of the stairs The Menagerie (and all subsequent home video releases of The Cage) include more screams by Vina, which were not in the 16mm version, there are a few places were music was added or removed…
And one of the strangest things is that The Menagerie includes 3 shots of Vina dancing which I can’t find in any official release and I can’t find the place where it should belong 😃
