Zoë Kravitz sure turned heads with the announcement of her directorial debut, a crazy island thriller initially titled “Pussy Island.” Eventually changed to the less provocative, more-marketable “Blink Twice” —a reference to being kidnapped and blinking to convey you’re in danger—the film is a psychological thriller about a cocktail waitress who becomes infatuated with a tech billionaire and travels with him to his private island, where things begin to go wrong.
