Fiennes, who makes his directorial debut (and stars in) with an adaptation of Shakespeare's "Coriolanus," will receive the Richard Harris Award, which recognizes contribution to British film by an actor.
Two-time Oscar nominee Fiennes, who wrapped up his role as big baddie Lord Voldemort in the "Harry Potter" movies in July and will co-star in the next James Bond flick, "Skyfall," joins a list of past Harris Award recipients that includes John Hurt, Daniel Day-Lewis, Jim Broadbent and Helena Bonham Carter.

Meanwhile, three-time Oscar nominee Kenneth Branagh will receive the Variety Award, for bringing international attention to the British film industry.
Branagh, who also played a role in the "Harry Potter" flicks — he was Professor Gilderoy Lockhart in "Harry Potter and the Chamber of Secrets" — is currently starring with Michelle Williams in "My Week With Marilyn." The actor also directed the action-adventure "Thor" earlier this year.
Three movies are tied for the most nominations at this year's British Independent Film Awards: "Shame," "Tinker Tailor Soldier Spy" and "Tyrannosaur," which each received seven nominations.
