Career: After graduating, Palin presented TV show Now! and worked in light entertainment. In 1966, he and Jones began writing for BBC comedy shows. Three years later, they joined forces with John Cleese, Graham Chapman, Eric Idle and Terry Gilliam to front ground-breaking sketch show Monty Python's Flying Circus. A huge hit, 45 episodes were made between 1969 and 1974, as well as five films. Palin has also starred in movies including A Fish Called Wanda, A Private Function, and American Friends (which he also wrote), and appeared in acclaimed TV drama GBH. Since the mid-1980s, he's become famous for globetrotting programmes such as Around the World in 80 Days and Pole to Pole. He's written books to accompany each series, as well as two novels; three volumes of his diaries have also been published. He delivered 2013's Royal Television Society lecture.

Career: Smith's charm swayed Quincy Jones and the NBC TV network to give him a starring role in The Fresh Prince Of Bel-Air, a series that ran for six years. In 1992, he made his film debut with Where the Day Takes You. Since then, he's enjoyed a steady string of box-office hits, including Bad Boys, Independence Day, Men in Black and its two sequels, and Ali, which gained him an Oscar nomination. Other projects include Enemy of the State, Six Degrees of Separation, I, Robot, I Am Legend, Seven Pounds and Hancock. His recent work includes Men in Black 3, After Earth, and new movie Focus.
