Lee Van Cleef was an American actor born in Somerville, New Jersey.  He was one of the great movie villains, whose distinctive hawk nose, steely glint in his eyes and perpetual snarl in the turn of his mouth destined him to play the heavy in some of the most memorable Westerns and action pictures of the 1950's and 60's.  Van Cleef appeared in 90 films and over 100 television series spanning nearly four decades.  Before breaking into films, during World War II, Van Cleef served in the United States Navy aboard minesweepers and subchasers.  Later, he had a brief career as an accountant and became involved in amateur theatrics in his spare time.  An audition for a professional role led to a touring company job in "Mr. Roberts."  His performance was seen by Stanley Kramer, who cast him as henchman Jack Colby in "High Noon" (1952), a role that brought him great recognition, despite having no dialogue in the film.  Over the next decade, he played a string of memorably villainous characters, primarily in Westerns but also in crime dramas such as "I Cover the Underworld" and "The Big Combo," both released in 1955.  He played another outlaw henchman in John Ford's "The Man Who Shot Liberty Valance" (1962).  In 1965, Sergio Leone cast him as the tough but decent Colonel Mortimer opposite Clint Eastwood in the Spaghetti Western, "For a Few Dollars More."  The following year, he portrayed the character Sentena/Angel Eyes in Leone's "The Good, The Bad and The Ugly" (1966).  The roles revitalized his flagging career, but now as a western hero, or at least an anti-hero, and he became an international star.  His later films, however, were of lesser quality.  In the 1980's he moved into action and martial-arts movies.

Lee Van Cleef appeared in four episodes of THE RIFLEMAN, portraying Dan Maury in "The Deadly Wait" (episode 26), Stinger in "The Prodigal" (episode 71), Wicks in "The Clarence Bibs Story" (episode 104), Johnny Drago in "Death Never Rides Alone" (episode 147).  He also co-starred with Chuck Connors in "Trial by Fear," an episode of "The DuPont Show with June Allyson" (1960), and in two episodes of Chuck Connors' later series, "Branded" (1965-1966).  Of his career, Van Cleef once quipped, " Being born with a pair of beady eyes was the best thing that ever happened to me."

Rhys Williams was a Welsh character actor in movies and television, whose career spanned the 1940's through 1970.  He made his film debut in "How Green Was My Valley" (1941).  Rural Wales was the setting of this John Ford classic film, and it featured a large cast of Welsh characters; although, it was actually filmed in Hollywood with American, Irish and Scottish actors.  Williams, who was the only genuine Welshman in the cast, originally was hired as a dialect coach for the other actors, but director John Ford gave Williams a role in the film.

Williams is recognizable to fans of the television series "Adventures of Superman," in which he played a sadistic character in one of the show's early episodes, "The Evil Three."  Other television appearances included CBS's anthology series, "The DuPont Show with June Allyson," co-starring Steve Allen in the 1960 episode "Play Acting," and five episodes of General Electric Theater between 1956 and 1961.  Williams also appeared in "The Donna Reed Show" (1958), "Temple Houston" (1963), "77 Sunset Strip" (1964), "Twelve O'Clock High" (1964-1966), "The F.B.I."
