Slam City is a short flash movie prequel to Pitch Black by animator Brian Murray with David Twohy which had been available for download at the Pitch Black website. Slam City is in the form of an official, confidential prison record detailing Riddick's arrival and escape from the Ursa Luna Slam city Facility in eleven hours twenty-two minutes. Notably, it shows Riddick undergoing the surgery that gives him "eyeshine" — the ability to see in the dark — and paying for this with a pack of Kool cigarettes as mentioned in Pitch Black. William J. Johns is seen at the end of the movie and is charged with capturing Riddick.
