Since the mid-’00s, California rock climber Alex Honnold has steadily built his repute for the "free solo"--ascending alone, without benefit of ropes, safety gear, or equipment of any kind. In 2017, he elected to tackle the formidable face of El Capitan in Yosemite National Park, and this dizzying, Oscar-winning documentary from Jimmy Chin and Elizabeth Chai Vasarhelyi ("Meru") captures the experience from his prep and personal misgivings through its astounding, record-breaking execution. 120 min. Widescreen; Soundtrack: English Dolby Digital 5.1; Subtitles: English (SDH).
