Ack! Where has this movie been all my life? St. Trinian's is the tall tale of a bevy of badass school girls who plot to steal the famous Vermeer painting "Girl with a Pearl Earring" so they can save their bankrupt school. Meanwhile, the Minister of Education, played by Colin Firth, is determined to make St. Trinian's over into a real school for young ladies. His former paramour is the headmistress Miss Fritton, played by Rupert Everett in drag. (Everett also exec produces.) And Russell Brand is, of course, a mad fellow in a bowler hat named Flash who enables the girls' shenanigans, like boozing and gambling. I'm digging the mischievous twins and the overall take no prisoners 'tude, but not so much the sexy high schoolers in stockings bit with model Lily Cole. Bond Girl Gemma Arterton stars as the lead gal Kelly, and Talulah Riley from The Boat That Rocked plays newcomer Annabelle Fritton.

St. Trinian's, which is based on the comics by Ronald Searle, has been out in the UK since 2007. There were also five previous iterations of St. Trinian's movies: The Belles of St. Trinian's,Blue Murder at St. Trinian's,The Great St. Trinian's Train Robbery,The Pure Hell of St. Trinian's, and The Wildcats of St. Trinian's.

A sequel, St Trinian's: The Legend of Fritton's Gold, is already in pre-production. St. Trinian's is slated to hit North American shores August 28th.
