The plot of St. Trinian's is as paper-thin as you'd expect, and serves merely as a platform for the anarchic actions of the cast of characters (some hokum about stealing a picture and saving the school). And a mischievous lot they prove to be: while they don't quite live up to the memories of the generation of St. Trinian's students before them, the primarily young cast still attack their roles with tremendous, and infectious, gusto.

And leading the cast is Rupert Everett, in an entertaining duel role at St. Trinian's headmistress Miss Frinton and her brother, Carnaby. Joined by Colin Firth, he's clearly having a whale of a time, and his casting process a wise decision. It's great to see the always-wonderful Celia Imrie in there, too.

St Trinian's, as you'd expect, has plenty of problems, notably a script that relies too much on the charm of its cast to pull it through. But heck, it's still fun, and a hard film not to enjoy. It won't win Oscars, but it will put a grin on your face. --Jon Foster
