During his days of prominence in the '80s, handsome, powerfully built American actor Gregory Harrison became the unofficial poster boy of the Catalina Island chamber of commerce. As a native of that offshore isle, Harrison frequently guested on talk and variety shows, elucidating the natural wonders of both Catalina and the Avalon resort. A graduate of New York's Actors Studio, Harrison briefly supported himself as a nightclub doorman before securing small film and TV roles. Harrison's most memorable credits were for the small screen: He played Logan 5 on Logan's Run (1977), Michael Sharpe on the final 1989-90 season of Falcon Crest, and the title role in the brief 1990 sitcom The Family Man. Harrison's longest TV-series run was seven seasons (1979-86) as "Gonzo" Gates, the Vietnam-vet doctor on Trapper John MD (1979-86). ~ Hal Erickson, All Movie Guide
