Alex Winter, the actor-turned-director best known for his role as Bill in the movie Bill and Ted's Excellent Adventure, is raising $75,000 on Kickstarter to make a documentary about the digital world that has been built around the virtual currency Bitcoin. He's also recruited the producer from the Academy Award-winning documentary Undefeated and the marketing strategist from Banksy's subversive film Exit Through the Gift Shop.

"Guns, drugs, and murder, and a new global currency that exists outside the control of government and banks," Winter says in the introduction to his Kickstarter promo. The film will explore Bitcoin, the recently-shuttered online drug bazaar Silk Road, and other hidden parts of the internet.

"Guns, drugs, and murder."

Winter, who also directed the Napster epic Downloaded, plans to interview "some of the greatest and most notorious minds in all areas of this story; hackers, innovators, politicians, free-thinkers and criminals" in order to get at the backstory behind what he believes is the most fascinating story of the decade. He's raised just over $7,000 for Deep Web: the Untold Story of Bitcoin and the Silk Road with 28 days to go before the campaign expires.
