Riley Keough, Jesse Eisenberg, Christophe Zajac-Denek, and their directors Nathan and David Zellner talk “Sasquatch Sunset” at Sundance. The cast and filmmakers stopped by the IndieWire Studio presented by Dropbox to discuss the film, a non-verbal exploration of a sasquatch family’s dynamic, which Eisenberg calls one of the five best scripts he’s ever read.
