I'm pretty sure that Peacock went straight to video, which is kind of a shame. It's a psychological thriller starring Cillian Murphy, Susan Sarandon, and Ellen Page about cross-dressing and train crashes and multiple personalities and politics. Here's the trailer:

I'm not saying that Peacock should have won an Oscar, but it's one of those quiet movies that hinges on a single performance, and Murphy is really exceptional. He's a tightly wound bundle of neuroses as a man, and as Emma, he quickly learns how to assert him/herself. The movie has its downsides—Page gives the flattest performance of her career—but for a rental you've never heard of before, it's a riveting, quality experience. You should rent it sometime soon.
