Though he usually is cast as an extra in numerous films, he is probably best known for portraying Crazy Ralph, the drunk old man who says "You're all doomed!" in Friday the 13th (1980) and Friday the 13th Part 2 (1981).
He was born in the Austro-Hungarian Empire, the son of Zofia (Kania) and Jan Górny, who were of Polish descent. The family moved to the U.S. when Walt was a small child, settling in Massachusetts.
