U.K. pop act Girls Aloud also takes a turn in the film.

Ealing also said that sales arm Ealing Studios International has sealed a deal with Concorde/ Telemunchen for German rights to "Trinian's," with Paradiso taking the film in Benelux. Entertainment Film Distributors is releasing it in the U.K.

"Concorde/Telemunchen's great track record in releasing British films make them our No. 1 choice for the German market," said Natalie Brenner, head of sales at Ealing Studios International.

"St. Trinian's" is produced and directed by Oliver Parker and Barnaby Thompson.

The comedy revolves around an infamous school for young ladies.

The project is supported by the U.K. Film Council's Premiere Fund.
