High tides, good vibes. Well, unless it’s Swedish director Ruben Östlund sending you out to sea. For his merciless, highly entertaining satire, he received the second Palme d’Or at this year’s Cannes Film Festival. A luxury cruise teeming with the super-wealthy runs into a massive thunderstorm—and is also hijacked by pirates. The few survivors are shipwrecked on an island, where social hierarchies must be renegotiated. Biting and jarring, Triangle of Sadness features Woody Harrelson as the Marxist captain who hosts an unforgettable dinner.
