Almost every time I watch a film for the second time I encounter a scene which seems to have been mysteriously messed up. I remember precisely how it was the first time I watched the film, but on the second occasion the dialogue and actions seem to have been changed so as to give an inferior overall result. I used to think that perhaps there were multiple versions of all these films, but every time I investigated I failed to discover any evidence of the existence of an alternative edition containing the details that I clearly remember, so I now think it's just the way my memory improves things. On the other hand, perhaps in some cases there really are different editions of the film that use different takes for certain scenes, though the films I watch twice are not usually the big-budget productions that are well-known for having multiple editions. Anyone else experience this?
