In Secret (2014)

"In Secret" is a period drama steeped in illicit desire, adapted from Zola's tale of adultery and obsession in 19th-century Paris. Oscar Isaac brings a simmering intensity to his role as the object of forbidden passion, and the tension between restraint and lust drives the whole affair. There's just 1 scene clipped from the film on site, but it delivers, catching Isaac in a genuinely explicit encounter that matches the story's illicit heat. For fans of the actor, it's a rare glimpse of him fully committing to the material's carnal edge.
