The Unlikely Story (2015)

The trailer tells the story of William Girven - an artist in Santa Monica who happens to be homeless. After meeting William, Ralf - an entrepreneur working out of a co-working space located across the street from William's nighttime bedroom - the vision arose to launch a kickstarter campaign to raise money for a movie to document an art exhibition of William's art at
CrossCampus. Hence the subtitle - From homelessness to prominence. More info at UnlikelyStoryLA.com
