Jude Law and Gambon to be honoured
Screen veteran Sir Michael will receive the Richard Harris Award, which recognises an actor's outstanding contribution to British film.
The award was set up in 2002 in honour of the late Irish actor.
Sir Michael stepped into his role as Hogwarts headmaster Dumbledore in the Harry Potter films after Richard died in 2002.
Jude Law will pick up the Variety Award which recognises an actor, director, writer or producer who has helped to focus the international spotlight on the UK.
The stars will receive their awards at a ceremony in London on December 9.
