This film really shows a viewer the variety of characters Cillian Murphy is capable of playing. Murphy plays a male as well as a female, both characters differing quite drastically from one another. The main character suffers from multiple-personality disorder, and the film portrayed it well. Not once does it belittle the disorder; instead, it shares with us a beautiful story I would recommend you experience.
Cillian Murphy is downright unmatchable. He can do things with a stare that I can't do with all of my body -- that no one can do. He proves here that he is one this generation's best actors, though he seems quite overlooked. He MADE the film (though the writing was gripping enough in and of itself). Quite impressive for a student film.
