I saw an advanced screening in Louisville of Zero Effect back in the day. Of course, after seeing it, it must have had a limited release because it was never released in Louisville--not that I know of, of course.
Anyway, there's an article in the AV Club about the influence that it has from the Sherlock Holmes stories.
I need to see that movie again. I haven't seen it since it came out. Jake Kasdan directed it. Since then, he's directed The TV Set, Walk Hard: The Dewey Cox Story, and select episodes of Freaks and Geeks.
