All evidence indicates that actor Michael Greene's first film assignment was an unbilled bit in 1965's The Cincinnati Kid. He continued accepting small roles into the 1970s, notably the motorcycle punk who gives Woody Allen a going-over in Play It Again Sam (1972) (curiously, Greene shows up in a later scene as a restaurant extra sitting directly across from Allen!). After several years' of faithful anonymous screen service, Greene was given a leading role in something called The Clones (1973) wherein Michael Greene plays a scientist who learns to his horror that he has been cloned by mad doctor Stanley Adams--thus paving the way for a climactic showdown between Greene and his synthetic look-alike.
