The film version of playwright Alan Bennett's The History Boys, this year's winner of Broadway's Tony award for best play, will have its Royal World Premiere attended by Prince Charles, the Prince of Wales, and his wife Camilla, the Duchess of Cornwall, in London on Oct. 2. The entire cast of the play -- and movie -- will fly to London from New York, where it ends its engagement on Oct. 1. The play also won awards for director Nicholas Hytner, actor Richard Griffiths, and actress Frances de la Tour. In addition, it won for sets and lighting, making it the most honored play on Broadway since 1949's Death of a Salesman. The film version, from Fox Searchlight, is scheduled for release in the U.S. on Nov. 22.
