The first instalment in Peter Jackson's Hobbit trilogy will play on the evening of Wednesday, December 12. This will be the 65th Royal Film Performance, which is an annual charity performance of a British film attended by members of the Royal Family.
Last year's performance was of Martin Scorsese's Hugo, while Jackson's last film The Lovely Bones played in 2009.
Proceeds from the event go to the Cinema and Television Benevolent Fund, a charity to help people in the film and television industries who encounter accident, illness, bereavement or unemployment.
The first performance was the Powell and Pressburger film A Matter of Life and Death in 1946.
A new trailer for The Hobbit was released last week in honour of Tolkien Week, while a new poster was released over the weekend.
