The film version of the Tony-award-winning play The History Boys received a command performance in London Monday night, just hours after the cast who appeared in both the play and the film made their final appearance on Broadway. The charity premiere was attended by Prince Charles and his wife Camilla, the Duchess of Cornwall. The cast members have been together since the play originally opened in 2004. In an interview with the BBC, Richard Griffiths, who received the best actor Tony this year, commented: "The ability to trust your fellows is enormously powerful and important on screen and on stage. It means you can push the limits, the possibilities of a scene way past what the author asked for." The film is due to open in the U.S. in November.
