Career: Majors made a string of appearances in TV shows and films such as Will Penny, The Alfred Hitchcock Hour and The Virginian. He spent four years in Western show The Big Valley, but it was The Six Million Dollar Man that made him a star in 1973. The series ran until 1978, and spawned spin-off The Bionic Woman, as well as a range of merchandise. Majors reprised the role of Steve Austin in 1987 for the first of three bionic-themed TV movies. He scored another small-screen hit in 1981 as crime-busting stuntman Colt Seavers in The Fall Guy and has since appeared in such movies as Scrooged and Big Fat Liar, and sitcom The Game.

Career: Despite some decent film roles, Ekland became famous for being married to Peter Sellers, and appeared with him in After the Fox and The Bobo. She had a small but memorable role in 1971 cult classic Get Carter. Two years later, she made The Wicker Man, which remains one of her most popular movies. Her Bond girl role in 1974's The Man with the Golden Gun sealed her reputation as a sex symbol and won her a lifetime of publicity. Few of her roles since have been memorable. She began appearing in British pantos in 1992 and has written a warts-and-all autobiography. She appeared in the 10th series of I'm a Celebrity... Get Me Out of Here! in 2010.

Career: McCallum became an assistant stage manager, but National Service interrupted his career. He made his film debut in 1957's These Dangerous Years, and appeared in numerous British movies before moving to Hollywood in the early 1960s. He landed roles in Billy Budd and The Great Escape but it was his performance as Illya Kuryakin in The Man from UNCLE that made him a household name in 1964. The series ran until 1968, and a spin-off TV movie was made in 1983. He also released four albums in the 1960s. Other major projects include Colditz, The Invisible Man, Sapphire and Steel, Mother Love, Hear My Song, and Cluedo. Since 2003, he has starred in popular American drama NCIS, playing forensics expert Dr Donald 'Ducky' Mallard.
