Career: Determined to become a serious actor, Grammer spent two years at New York's Juilliard School. He then worked in theatre before making his TV debut in 1983 miniseries Kennedy. He had a stint in soap Another World, and in 1984 began playing Dr Frasier Crane in Cheers. After Cheers ended in 1993, he launched the hugely popular spin-off series Frasier. In addition to starring in 264 editions of the sitcom, he directed more than 30 episodes. Grammer has also starred in X-Men: The Last Stand, short-lived sitcoms Back to You and Hank, and the dramas Boss and Partners. He is also the voice of Sideshow Bob in The Simpsons.

Career: David worked steadily on the stage throughout the 1980s and made his film debut in Bright Lights, Big City in 1988. He was later offered a role in Little Man Tate by former Yale classmate Jodie Foster, who remembered him from a student play. In 1992, he was in short-lived sitcom The Powers That Be and caught the eye of Frasier's creators, who noticed his resemblance to Kelsey Grammer and wrote the role of Niles especially for him. His performance in the long-running sitcom earned him four Emmy awards and a reported salary of $1million per episode for the last few seasons. Frasier came to an end in 2003 and David has since been seen in the film Down With Love and in various stage productions on Broadway and the West End. He won a Tony Award in 2007 for his performance in Kander and Ebb musical Curtains.
