Diane McBain (born May 18, 1941) is an American actress who, as a Warner Brothers contract player, reached a brief peak of popularity during the early 1960s. She is best known for playing an adventurous socialite in the 1960-62 TV series Surfside 6 and as one of Elvis Presley's leading ladies in 1966's Spinout.
A native of Cleveland, Ohio, McBain moved to the Hollywood area at an early age and began her show business career as an adolescent model in print and television advertisements. During her senior year at Glendale High School, while appearing in a Los Angeles play, she was spotted by a Warner Bros talent scout and added to the studio's roster of contract performers who were appearing in an assembly line-style mass production of TV episodes and theatrical features.
Starting with the September 13, 1955, premiere of the hour-long, three-shows-in-one Warner Brothers Presents, the studio's TV arm, Warner Brothers Television, provided ABC with nearly 20 shows, including seven Western and four detective series. At the age of 17, she was immediately put to work, making her TV acting debut in two episodes of Maverick, March 8 with Jack Kelly and November 22, 1959, with James Garner, as well as the October 16 episode of 77 Sunset Strip. Her first director, at the helm of the March 8 installment, "Passage to Fort Doom", was veteran actor Paul Henreid.
