Guy Williams (born Armando Joseph Catalano; January 14, 1924 – April 30, 1989) was an American actor and former fashion model.
He usually played swashbuckling action heroes in the 1950s and 1960s, but never quite achieved movie-star status, despite his appearance (including hazel eyes, 6'?3? [1m 90 cm] height, and 190 lb [86 kg] weight) and charisma, which helped launch his early successful photographic modeling career.
Among his most notable achievements were two TV series: Zorro in the title role, and as the father of the Robinson family on the popular sci-fi series Lost in Space.
During most of the 1970s, Guy Williams frequently visited and worked in television shows in Argentina, where he was most revered.
He retired in the early 1980s in Buenos Aires, where he died of a brain aneurysm in 1989.
