Greg Harrison

He has played the lead in a touring version of the musical Chicago and was the male lead in each film of the Au Pair trilogy. He also appeared as Benjamin Stone in the Broadway revival of Stephen Sondheim's Follies and created a role in the original Broadway production of Kander & Ebb's Steel Pier. In 2011 he had a guest starring role as a doctor on ABC's Body of Proof.

In 1979, after years of being a relatively unknown actor, Harrison finally won the role of surgeon, Dr. George "Gonzo" Gates on Trapper John, M.D., starring opposite Pernell Roberts on the medical drama spun off from M*A*S*H. Harrison had guest starred on an episode of M*A*S*H the year after Wayne Rogers departed from his role as Trapper John on that series. Harrison remained as Gonzo on Trapper John until the middle of the show's seventh season, when he decided to leave for other ventures. The series continued for several more episodes without Harrison, but concluded its run at the end of the 1985–86 season. Harrison had been a fan of Roberts' role as the eldest son of the Cartwright family on the series Bonanza (1959–1973). The two remained friends until Roberts' death from pancreatic cancer on January 24, 2010.

Harrison later joined the cast of NBC's Sisters for the 1994–95 season, playing Daniel Albright. In 1996, he starred opposite Eric Roberts in It's My Party, a film based on the true events of a man diagnosed with AIDS who planned a two-day party to say goodbye to his friends and family, and who then took his own life with pills.

Harrison's later role as stripper John Phillips in the 1981 TV movie For Ladies Only made him a favorite with women and gay men in the 1980s. He spoofed that role in the 1986 miniseries Fresno where his character appeared shirtless at every opportunity. Fresno was also a spoof of the prime-time series, Falcon Crest, where Harrison became a regular three years later in the final season (1989–90), opposite Jane Wyman, who was absent for nearly the remainder of the last season, due to her unhappiness with the direction her show was going. As Falcon Crest ended production in early 1990, the series' parent studio, Lorimar Television, cast Harrison in its upcoming CBS sitcom The Family Man, from producers Thomas L. Miller and Robert L. Boyett. The series, which premiered that fall, featured Harrison as a single fireman father raising his four kids with the help of his father-in-law, played by Al Molinaro. Despite a few attempts by CBS to help it build an audience, The Family Man was cancelled after one season.

Harrison has been married since 1980 to actress Randi Oakes. The couple have four children, three girls and a boy. He lived in Gold Beach, Oregon, for 15 years; as of 2007, he lives in Eugene. He enjoys surfing and golf.

Harrison became addicted to cocaine during the 1980s and was able to break the addiction with the help of the Betty Ford Center.

He was the title character on the 1977–78 science fiction series Logan's Run, after which he played the role of Levi Zendt on the 1978 NBC miniseries Centennial.
