A former physical culture model, handsome, blond Ken Clark (born Kenneth Donovan Clark) gave Richard Egan a run for his money in the beefcake sweepstakes at 20th Century Fox in the mid-'50s. But Clark, who also appeared on such television shows as The Jack Benny Program and Schlitz Playhouse of Stars, was dropped by Fox after Love Me Tender (1956, with Egan and, in his screen debut, Elvis Presley). He then drifted into low-budget fare, including what proved to be his most memorable film, the Roger Corman thriller Attack of the Giant Leeches (1959). After the failure of a proposed TV series -- Brock Callahan, based upon a character in William Campbell Gault's detective novels -- Clark went Europe, where he starred in such fare as Arizona Bill (1964) and as Agent 077 in two 1965 Italian spy movies. He resumed his Hollywood career in the '80s with such productions as Twice in a Lifetime (1985) and the mini-series Invasion (aka Robin Cook's Invasion) in 1997.
