In what is said to be “the world’s first feature film to debut on mobile phones”, Sally Potter’s RAGE is being distributed in seven episodes on Babelgum. Starting at 12:01 EDT on September 21, you can begin pulling down an episode a day for a week, provided you have an iPhone, iPod Touch or Google Android-based phone.

The movie includes some big names, including Eddie Izzard, Steve Buscemi, Dame Judi Dench and Jude Law, and is an ode to the fashion industry.

We’re curious to see how it’ll do; though we think they’re shooting themselves in the foot by turning their backs on all of the other phones in captivity that can play back 3GPP video… including, hello, the BLACKBERRY?! Then again, the flipside is that this movie will be so well-received that everyone who can will be downloading it, bringing the Internet to its knees (and possibly even T-Mobile and AT&T’s 3G networks as well.)
