P.h.D. physics student Luke Thompson decided to use his access to CERN to make a zombie movie chock full of science humor. Using a crew of less than 20 people and a budget under $4,000, Thompson spent two years making Decay before deciding to release it for free online under a Creative Commons license.
Says Thompson to Wired, "We’ve been given a great and rare opportunity to have fun and make something awesome, so making money was never the point. We’re hugely proud of what we’ve achieved — the fact is that it’s a no-budget indie and there’s no reason to expect we’d sell more than a few hundred copies. So we’d rather our two years of work was seen by more people by releasing it for free.”
