Christopher Lee's Dracula had a tendency to burst into flame in sunlight, but I do believe that idea well predated even him -- as I recall that's essentially how the vampire in Nosferatu was waxed in 1922...he's convinced to stick around long enough that the sun comes up and flash-fries him. I'm trying to remember what happens in Herzog's Nosferatu -- I vaguely recall him turning into a shadow on the wall when the sun rises.
