Father of stuntman Robert Prohaska. Best known for playing "animal"
roles, typically gorillas and bears. He played Cookie Bear
on The Andy Williams Show (1969). Besides sculpting
highly-detailed ape and bear masks, Prohaska designed a wide variety of non-anthromorphic costumes to avoid the "man in a suit" concept. His work included the Horta for the original Trek episode "Devil in the Dark", and for The Outer Limits (original series) he designed a reverse-jointed Thetan alien (accomplished with the aid of stilts) and an amoeba (the "Mikie").
Byron Haskin, director of the Outer Limits episode "The Architects of Fear", claimed, "When I first met Janos, he came into my office, put a beer bottle on the table, and then stood on his head with his finger in the bottle, supporting himself. He could defy the law of gravity." (Outer Limits Companion, pg. 81).
Prohaska maintained a workshop in Santa Monica up to the time of his death from which he did most of his greatest work.
