Dack Rambo

With his movie-star good looks and marquee-ready stage name, Dack Rambo was a below-the-radar talent who never ascended to the level of being a household name. The native Californian had a twin brother, Orman Ray "Dirk" Rambo, who died in a 1967 traffic accident. Discovered by actress Loretta Young, the siblings were cast in her 1962 CBS sitcom, "The New Loretta Young Show." Towards the end of the 1960s, Rambo's rugged swagger landed him parts in the television westerns "The Guns of Will Sonnett" and "Gunsmoke." Over the next decade, it wasn't a stretch for him to transition into guest spots on hour-long criminal and action series like "Cannon," "Wonder Woman," and " Charlie's Angels." Rambo even starred in the one-season 1978 NBC action series "Sword of Justice" as playboy mercenary Jack Cole. During the 1980s, he made the leap over to primetime and daytime soap operas, appearing in "All My Children," "Hotel," "Paper Dolls," and "Dallas," where he played cousin Jack Ewing from 1985 through 1987. During his final role as Grant Harrison on "Another World," Rambo was diagnosed HIV positive. He quit the series, retired from acting, and publicly proclaimed his bisexuality and the fact that he was HIV positive. He died of complications from AIDS at the age of 52.
