St Trinian's film to premiere in London tonight

The movie revival of the classic British comedy series 'St Trinian’s' receives it world premiere in London tonight.

Fans are expected to throng Leicester Square to see the star-studded cast which includes Colin Firth, Rupert Everett, Russell Brand, Stephen Fry, pop band Girls Aloud, and OC actress Mischa Barton.

The co-director of the hotly-anticipated film, Barnaby Thompson, has described it as the “antidote” to Harry Potter in its depiction of British public school life.

Other stars of the movie, which was filmed in and around London, include Jodie Whittaker, Lily Cole and Celia Imrie.

The original cast featured George Cole, Alastair Sim and Joyce Grenfell.

The St Trinian’s stories began life as cartoons by Ronald Searle. The first film, 'The Belles of St Trinian’s', was released in 1954 and spawned several sequels.

Despite featuring sex and drugs the new St Trinian’s movie will break with tradition – the students will never be seen smoking.

The previous St Trinian’s students were notorious for enjoying cigarettes.
