‘Anne at 13,000 ft’: Film Review
A riveting and radical act of empathy, with actress Deragh Campbell’s unforgettably embodied portrayal of mental instability as the eye of its storm, Canadian director Kazik Radwanski’s astonishing third feature (after “How Heavy This Hammer” and “Tower”) is a brief, bracing burst of microbudget indie filmmaking at its most powerful. “Anne at 13,000 ft” might look like mumblecore, but it plays as a psychological horror and a ticking-clock thriller that morphs into a wild, windswept tangle of incipient, but never quite arriving tragedy.
