Gary Lockwood (born February 21, 1937) is an American actor probably best known for his iconic 1968 role as the astronaut Dr. Frank Poole in 2001: A Space Odyssey. Born in Van Nuys in the San Fernando Valley of southern California, Lockwood's birth name was John Gary Yusolfsky. He attended the University of California at Los Angeles on a football scholarship. He was married to Stefanie Powers in the 1960s and Denise DuBarry in the 1980s. Lockwood was a movie stuntman, and a stand-in for Anthony Perkins prior to his acting debut in 1959 in an uncredited bit role in Warlock. Lockwood's two series came early in his career, and each lasted only a single season. ABC's Hawaii-set Follow the Sun (1961–62) cast him in support of Brett Halsey and Barry Coe, who played adventurous magazine writers based in Honolulu. Lockwood was Eric Jason, who did the legwork for their articles, but his on-screen time was limited since most of the plot focused on Halsey or Coe. In the story, Lockwood was said to have been born on December 7, 1941 (Pearl Harbor Day), but he was actually born nearly five years earlier.
