On September 3, 2017, Adam Ondra completed Silence in Norway's Flatanger Cave. He graded the route, formerly known as "Project Hard," 9c (5.15d), which would make it the hardest pitch in the world. Watch a teaser for the upcoming film above. On Facebook, Ondra announced that the film will premiere on February 23 in Arco, Italy. The event, including the full film, will be livestreamed, and then Silence will be available on Youtube. We'll share the movie on Climbing.com when it's ready.
