In Secret (2013)

A woman seeks relief from her monotonous life in the arms of a stranger in the crime thriller In Secret (2013). In 1860s Paris, Therese Raquin (Elizabeth Olsen) is a beautiful but repressed housewife trapped in a loveless arranged marriage with her feeble cousin Camille (Tom Felton). Camille's overbearing mother Madame Raquin (Jessica Lange) dominates both of their lives, an arrangement that Therese resents. So when Therese strikes up an affair with her husband's friend Laurent (Oscar Isaac), it's out of spite as much as passion. But no matter the motivation, any occasion to ogle Oscar Isaac’s sweet ass is a revelation. Wish we could’ve seen Oscar’s wiener, but it’s no secret that his backside is sweet!
