To the best of my knowledge, it's only opening in New York and LA (and Pasadena), but there may be others and there will probably be more sometime in the near future. I'm not sure. You should keep an eye on your local theater listings to find out. Or maybe check out the movie's Facebook page if you're into that sort of thing.
In LA, it'll be playing at the Laemmle Sunset 5 in West Hollywood and the Laemmle Playhouse 7 in Pasadena.
You can watch the trailer and check out some fanastic looking stills at the official website.
