Career: While working in a department store in LA, Lansbury met a casting director through her mother. He offered her a role in the 1944 film Gaslight; she was just 18, but it landed her an Oscar nomination. Roles in National Velvet, Blue Hawaii and Bedknobs and Broomsticks followed. She gained further Academy Award nominations for The Picture of Dorian Gray and The Manchurian Candidate. She's also worked extensively on stage, winning a record five Tony Awards. But it was playing Jessica Fletcher in the long-running TV series Murder, She Wrote, that turned her into a household name. More recently, Lansbury has appeared in Nanny McPhee and Mr Popper's Penguins.

Career: Takei's big break came in 1965 when he was cast as Hikaru Sulu in the second pilot episode for Gene Roddenberry's series Star Trek. He was due to have a bigger role in the series but filming on The Green Berets (1968) meant the character Pavel Chekov was brought in to share helmsman duties. They eventually ended up sharing the bridge in one of the world's most successful sci-fi shows. After the series was cancelled, Takei became a regular on the convention circuit, eventually returning with the rest of the cast for Star Trek: The Motion Picture in 1979. Five films later, he officially hung up Sulu's uniform for good, but did return for a fan-based internet series. Other roles have included 3rd Rock From the Sun, Heroes, the film Prisoners of the Sun (1990) and Will and Grace. He also came third in the 2008 season of I'm A Celebrity... Get Me Out of Here!
