From Wikipedia, the free encyclopedia. Gary Grimes (born June 2, 1955, in San Francisco) is an American actor. Gary Grimes first major role was in the 1971 motion picture Summer of 42, playing a teenager who has an affair with a beautiful older woman, played by Jennifer ONeill. For that role, Grimes was nominated in 1972 for a Golden Globe Award as Most Promising Newcomer—Male and a BAFTA Award as Best Newcomer. Grimes also starred in the sequel Class of 44 (1973), which followed his character to college. Grimes other movie credits include Cahill U.S. Marshal (1973) alongside John Wayne, The Spikes Gang (1974) with Lee Marvin and Ron Howard and the cult Disney film Gus (1976), about a mule that kicks field goals. He was offered a TV series during that time period, but turned it down. Grimes retired from show business in the late 1970s, still lives in Los Angeles and has remained out of public view since that time. I got to the point where the work wasnt up to the quality that I wanted, Grimes told American Profile magazine in 2011. Im very happy in my decision.
