While not a silent film, the movie Le Dernier Combat has absolutely no dialogue, and is worth seeing. French black and white post-apocalyptic science fiction:
mhendo, I haven’t visited that site, but I’ll bet any money the versions there aren’t the restored versions. Spend the extra money if necessary and watch the restored versions – it’s well worth it. The full Lost World blows the normal incomplete version out of the water. The better picture quality of the restored Metropolis, Nosferatu, and Phantom of the Opera make the easily-available “standard” versions look like utter garbage. I used to find excuses not to show friends my old copies of Metropolis, until I got a copy of Giorgio Moroder’s restored version. The restored title sequence alone was worth watching the whole thing for. The newest restored version of Metropolis is even clearer and longer than Moroder’s.
