In this loose remake of Jacques Deray's languidly erotic 1969 thriller La Piscine, a glam rock superstar (Tilda Swinton) and her documentary filmmaking lover (Matthias Schoenaerts) retreat to the isolated Mediterranean island of Pantelleria. But their quiet vacation is soon crashed by a loud, libidinous record producer (Ralph Fiennes) and his Lolita-like daughter (Dakota Johnson from 50 Shades of Grey). The visit kicks off some nostalgic flashbacks and a bunch of questionable behavior. Where it all ends up is at the whims of the slow-burning script. But there's plenty of nudity and crackerjack acting to keep things interesting, even when the script fails to deliver on its ominous promise.125 minutes R.
