Sven- The Invisible Ray (1936)

 

From Wiki- The Invisible Ray is a 1936 American science-fiction horror film directed by Lambert Hillyer. It stars Boris Karloff as Dr. Janos Rukh, a scientist who comes in contact with a meteorite composed of an element known as "Radium X". After exposure to its rays begins to make him glow in the dark, his touch becomes deadly, and he begins to be slowly driven mad.  He ends up going out in a burst of flame.  I guess it is better to burn out than to fade away, my my , hey hey,

This is a gorgeous black and white movie.  Hand of Death, from 1962, resembles this movie, though that is far sleazier.  The performances here are really good, and it is well shot.  The effects are pretty good, though mostly just superimposed glowing and some in camera light effects.  Good movie.
