Two years (almost to the day) after 20th Century Fox hit the jackpot with David Fincher’s Gone Girl (2014), Universal Pictures releases a clone, also adapted from a best-selling mystery novel and trading in the dark secrets of beautiful, upper-class white people. Emily Blunt is the title character, a blackout drunk whose husband has thrown her out of their fancy home (which she passes every day on her commute), married another woman, and fathered a child. When the couple’s nanny turns up dead, the cops suspect the nanny’s husband, the psychotherapist she was humping, and Blunt’s character, who can’t remember what happened on the night of the murder. Like the Fincher movie, this plays with the idea that the hero may actually be the villain; unlike the Fincher movie, which was built like a Swiss watch, this gradually turns into a tangle of flashbacks as it races toward a fairly predictable conclusion. Tate Taylor (The Help, Get On Up) directed; with too much of Haley Bennett, Rebecca Ferguson, and Justin Theroux and too little of Allison Janney and Lisa Kudrow.
