has just received this exclusive final U.S. one-sheet for St.Trinian's, the British comedy that boasts a whole mixture of Brit talent from Talulah Riley and Gemma Arterton to Rupert Everett, Colin Firth, Russell Brand, and Lena Headey.

Directed by Oliver Parker and Barnaby Thompson, the film focuses on St. Trinians, a girls' school full of ne'er do wells run by headmistress Camilla Fritton (played by Everett ... in drag no less, he's one in from the left). There are two big problems facing the school: One, it's broke. Two, Fritton's ex-flame (Firth), who's also the Education Minister, isn't keen on her insistence on "free expression and self-empowerment." He's the Umbridge to Everett's Dumbledore, if Hogwarts had some hanky panky behind the scenes. Of course, these girls don't want to lose their school, so they decide to steal the famous "Girl with a Pearl Earring" painting from the National Gallery and save the day.

Between two of the UK's big romance men having a sexy past together, and girls whose badness extends well beyond short skirts and lipstick, this should be a fun ride. Trinian's was released a few years ago in the UK, but we'll finally get to see the bad girls in action stateside when it hits theaters on August 28. Scope out the poster below.
