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: Smith rose to prominence on stage during the 1950s thanks to regular West End roles. Her first film, 1956's Child in the House, didn't set the box office alight, but she eventually gained international acclaim thanks to her role in Othello nine years later. She won an Oscar for 1969's The Prime of Miss Jean Brodie and has since appeared in such acclaimed productions as California Suite (for which she picked up another Academy Award), A Room with a View, and Gosford Park. She became a Dame of the British Empire in 1990. More recently, Smith gained a new fan base thanks to her role as Professor Minerva McGonagall in the Harry Potter movies, appeared in the films Ladies in Lavender and Keeping Mum, and TV series Downton Abbey. She has also battled breast cancer.

Career: Her big break came in the terrifying film Rosemary's Baby (1968) by Roman Polanski. She showed her talent also on TV and at the theatre, but her final breakthrough was when she met Woody Allen and became his Muse after the film A Midsummer Night's Sex Comedy (1982). She and Woody Allen made 13 movies together before their accrimonious divorce. She has appeared in films sparingly in recent years, devoting her time to charity work and political activism. She is involved in humanitarian activities in Darfur, Chad, and the Central African Republic. In 2008, Time magazine named her one of the most influential people in the world.
