He had moved there 12 years ago after living in New York. He originally had come to this country in 1937.

Born in Vienna, Austria, Mr. Homolka scored his first theatrical triumph as "Richard III" there. He had a repertory career in Munich and Berlin, performing for nine years under Max Reinharct. His roles included a portrayal of "The Emperor Jones."

Mr. Homolka fled Germany and Austria because of the Nazis. He moved to England, where he appeared in such plays as "Close Quarters" and "The Power and the Glory" and such films as "Rhodes of Africa" and "I Married a Murderer."
