The film is called Miracle Park, and it's being described as a cross between the X-men and Trainspotting. Seriously. It's being shot using handheld cameras in Scotland as we speak. The plot involves animal rights activists who discover a secret government base beneath a low-level research facility.
This one's being produced on the cheap, and there's no word on distribution as of yet. I'm assuming that with Millar's name attached we can expect some sort of theatrical release here in the States. Check out the photos, courtesy of the fine folks at IGN.
