Love a good, sexy movie about an affair where one spouse ends up dead? Then here's In Secret (formerly known as Thérèse), which is based on the 19th-century novel Thérèse Raquin by Emile Zola. Elizabeth Olsen plays Thérèse, who is forced into an unhappy marriage to her cousin Camille (Harry Potter's Tom Felton) and soon falls easily into the arms of sexy painter Laurent (Oscar Isaac). When their affair heats up, Camille ends up dead at the hands of the lovers. Riddled with guilt, Thérèse can't exactly move on with Laurent, though she tries. Part of that inability is due to the snooping around of Camille's suspicious, grieving mother (Jessica Lange).
It's fun seeing Lange out of American Horror Story but still stirring up trouble, and Isaac and Olsen's chemistry is particularly scorching, even for the 1800s. In Secret comes out Feb. 21, and you can watch the trailer after the jump.
