Joseph Marcell was born in St. Lucia and came to England with his parents at the age of 7.
Before he became an actor, he was doing industrial training at Southampton Power Station while it was under construction and going to college at Wandsworth Tech.
His training included studying with Nina Finbergh in Hampstead and then joining Shakespeare and Company in Lenox, Massachusetts in the USA (the theatre company set up by ex-RSC actress Tina Packer).
Marcell was a member of the cast of Empire Road, the first television series to have been written and directed by people of Afro-Caribbean origin although he is probably best known internationally for his role in the NBC series The Fresh Prince of Bel-Air.
His credits also include playing the title role in Peer Gynt at the National Theatre in 2000; Willy Loman in Arthur Miller's Death of a Salesman at the Haymarket Theatre, Leicester; Ira Aldridge in Black Star at the Octagon Theatre, Bolton. He was credited as Joe Marcell early in his career.
