The Serpent (15)

This coiled revenge thriller has moments of genuine terror and intrigue.

Yvan Attal plays a fashion photographer going through a painful divorce when he finds himself on the end of a blackmail scam engineered by a psychopathic ex-classmate (Clovis Cornillac) in revenge for a prank 30 years before. Attal's portrait of a desperate, cornered man is convincingly done, and the fiendish twists of the plot are genuinely exciting.
