I watched quite a few ZORRO episodes tonight. The shows look very, very good (though not perfect; there are dust specks from time to time and some light print damage or flickering occasionally; the sound is sometimes a bit off, too: flutter on some episodes and one episode I watched seemed to have been more than half the show looped, and the ADR work gave it a very dry, dead sound.
What fun to see the handsome Guy Williams at his absolute physical peak. The image is so sharp, however, that his stunt double is often very noticeable (a very handsome man himself).
