Actor Robert Walker Jr., perhaps best known as the troubled Charlie Evans from the classic Star Trek episode Charlie X (1966), dies at the age of 79. The son of a Hollywood acting power couple, Walker was expected from an early age to follow in his father’s footsteps; even after his parents divorced, his new stepfather, David O. Selznick, was a guiding force in his career. Early attempts at movie breakout roles proved less than successful, but Walker made a huge impression on TV audiences, with memorable appearances on Star Trek, The Invaders, and The Time Tunnel in rapid succession; movie success did eventually follow in such films as 1969’s Easy Rider and 1972’s Beware! The Blob, but it was television that provided much of his work. Later TV appearances included guest roles on The Six Million Dollar Man, CHiPs, Dallas, In The Heat Of The Night, and L.A. Law.
