Trivia: Though he regularly worked on screen, stage, and television, veteran British actor Jon Pertwee may best be remembered for playing the third Dr. Who in the long-running British sci-fi television series of the same name from 1970 to 1974. The son of actor Roland Pertwee, he started out on-stage and then made his feature film debut in A Yank at Oxford (1937). A string of popular films followed, but Pertwee temporarily abandoned movies to serve with the British Navy during WWII. Upon his return, he reestablished his film career and subsequently proved himself a gifted and multi-talented artist; while appearing in a series of Carry On films, he was compared to Danny Kaye. After leaving the Dr. Who series, Pertwee appeared in several London West End musicals and also returned to feature films such as One of Our Dinosaurs Is Missing and The House That Dripped Blood (1971). In 1978, Pertwee became the homeless but lovable bum Worzel Gummedge on the children's show Worzel Gummedge. Up until the time of his death on May 20, 1996, Pertwee enjoyed making guest appearances at Dr. Who conventions.

Trivia: Danced with the Royal Ballet at the age of 5. Co-starred with future British Member of Parliament Edwina Currie in a primary-school production of Alice Through the Looking Glass. Worked so well as a stage assistant at Liverpool Playhouse that she would make intentional mistakes to better her chances at acting. Met husband Brian while performing in the role of a corpse in a 1966 stage production of The Physicists. Held her wedding reception on famed Penny Lane and often attended Liverpool football (soccer) matches at Anfield. Played companion Sarah Jane Smith on Doctor Who opposite Jon Pertwee and Tom Baker in the 1970s; later reprised the role for The Sarah Jane Adventures in 2007.

Trivia: Nicholas Courtney was a longtime working actor in England, portraying dozens of leading and supporting roles in theater, television, and movies -- but he was most well known around the world, as well as in England, for playing Brigadier Alistair Gordon Lethbridge-Stewart on the long-running BBC series Doctor Who. The son of a British diplomat, he was born in Cairo, Egypt. His father had been a career military man before entering the diplomatic service, and one of his uncles was an Air Chief Marshall in the Royal Air Force -- and although Courtney never aspired to a military career, he did observe their respective behavior, which served him well later in life. Courtney turned to acting after 18 months in the British army. With extensive stage experience behind him, he made his television debut in 1957, and quickly moved into motion pictures as well. He was busy in film and, especially, television over the next decade, including a role in a 1965 episode of Doctor Who as Space Security Agent Bret Vyon, working alongside original series star William Hartnell. That performance impressed the producers sufficiently so that, when planning the series' 1968 run, as a result of a last-minute shift in another actor's availability, Courtney inherited the part of Colonel (later Brigadier) Lethbridge-Stewart. This proved to be the role of a lifetime, as the co-star of one of the BBC's most popular series. Courtney brought his acting experience, as well as his recollections of his father's and uncle's approaches to their respective careers to his portrayal. The brigadier is the head of a top-secret military division known as UNIT (United Nations Intelligence Taskforce), organized to investigate and deal with threats that fall outside of the range and experience of the conventional military and intelligence services. Courtney symbolized cool British professionalism and efficiency, bringing a good deal of humanity to the portrayal and never letting the character of the brigadier turn into caricature. He proved extremely popular with both the viewers and the producers, and went on to portray the UNIT leader in dozens upon dozens of episodes of the series across the next decade or more. Courtney ultimately played hundreds of roles in a career of nearly 50 years on the stage, in films, and on television -- including regular work in such popular series as The Two Ronnies, and appearances during the 1960s on The Champions and The Avengers -- but it would be Lethbridge-Stewart by which he would be best known around the world. And his fame was sufficient to justify his writing an autobiography, Five Rounds Rapid (1998), which he updated in 2005 as Still Getting Away With It. He passed away in 2011 after a long illness.

Trivia: Bennett, a British character actor, has been onscreen from 1960.
