Dean Potter: The Core

A portrait of Dean Potter and the life he built inside Yosemite Valley: rock climbing, slacklining, and highlining, with Valley granite as workplace and as home. The film's centerpiece is his free climbing of Half Dome and El Capitan in a single day, two of the most iconic big walls anywhere, linked in one push. It runs long enough to sit with Potter rather than summarize him, which is the reason to watch it. If you know him mainly from the 2015 wingsuit accident that killed him, this is the other side of the record: the daily practice, the lines strung across empty air, and the valley he kept coming back to.
