Alex Winter’s new documentary “Deep Web: The Untold Story of BitCoin & The Silk Road,” screened at the San Francisco International Film Festival, which is where we caught up with him to talk about the film. The film is about Ross Ulbicht, Silk Road, an underground market place, the war on drugs and privacy.

Ulbricht was “convicted of being the Dread Pirate Roberts, secret mastermind of the Silk Road online narcotics empire,” writes Wired. Ross is serving time in jail and is waiting for the final verdict, which will be announced towards the end of May 2015.

Winter wrote, directed and co-produced the film. Keanu Reeves provides the commentary for the film.

This is a highlight of a longer interview with Winter that we will publish later this month.
