** (two stars)
"The Sleepwalker" is a gorgeously photographed mess, an erotic head-scratcher with pretentions of Bergman-esque grandeur. Kaya (Gitte Witt) and her boyfriend Andrew (Christopher Abbott) are fixing up her family's house in rural Massachusetts. Then Kaya's half-sister Christine (Stephanie Ellis) shows up unexpectedly, and with news that she's pregnant and has a fiancé, Ira (Brady Corbet), who shows up a day later. Over the next few days, family secrets are revealed about an incident in Kaya and Christine's past. Director Mona Fastvold (who co-wrote the script with Corbet) aims for a dreamlike atmosphere of menace, but the murky plotting undoes those ambitions. Props, though, for Zachary Galler's lush cinematography and an evocative score by Sondre Lerche (Fastvold's husband) and Kato Adland.
