Marty Feldman

Marty Feldman (1934--1982) was an English comedian, comedy writer and actor recognisable for his enormous, protuberant eyes (the result of an overactive thyroid). After writing for The Frost Report and co-creating At Last the 1948 Show, he found international fame as the hunchbacked assistant Igor in Mel Brooks's Young Frankenstein (1974), and went on to lead his own films Silent Movie (1976) and The Last Remake of Beau Geste (1977) (Wikipedia)
