In the movie Mandy, Nicolas Cage and Andrea Riseborough live in remote tranquility until an absolutely bananas cult kidnaps her. There’s endless screaming and blood and even a chainsaw fight, but to tell you much more would defeat the show-all extravaganza of writer-director Panos Cosmatos’s heavy-metal horror nightmare. Suffice to say this is a movie, as Vulture’s Kyle Buchanan said after a Sundance Film Festival screening, “where Nicolas Cage slays a demon alien and then does a huge line of cocaine, but that almost seems redundant. Nicolas Cage doesn’t need to do cocaine to get lit. Cocaine ought to try Nicolas Cage.” Mandy premieres on September 14.
