A romance and a breakup between two girls develop into a mutiny at an all-girl boarding school--this sounds extremely familiar, but the outcome of Lost and Delirious is not, thanks to the fact that the film is neither the filmmaker Lea Pool's semi-autobiography nor one of her earlier works. As a veteran filmmaker, Pool puts a distance between the characters and herself; it produces a tone that is neither too emotional nor too objective. The contemporary touch is made subtly but noticeably, as the story takes place at a school where the girls play soccer and the teachers accept students' openly discussing love and sex in a classroom. The incredible acting of two leads, Piper Perabo and Jessica Paré, makes the girls believable. They look similar with each other; the combined castings may be called a mistake as it could confuse the viewers at least in the beginning.
