In 1967 there was a UK television mini-series adaptation of Les Misérables, which was in black and white and ran for eight hours. I haven't been able to find this version but many scenes of it are shown on a documentary that I just found on Youtube.
For pictures of the 1967 UK adaptation click here, then on photos, then on albums, then on "Les Misérables, 1967, Inglaterra ??":
I have not watched the documentary yet but I'm pretty excited to watch these scenes. The Learning Channel had a documentary show called Great Books and in one of the episodes Les Misérables was discussed, and that is what the first link is. I recommend downloading the documentary, since who knows when it will get removed.
