Movies like l'amant double

L'Amant double (released in the United States as Double Lover) is a 2017 erotic thriller drama film written and directed by François Ozon, based on the 1987 novel Lives of the Twins (also known as Kindred Passions) by Joyce Carol Oates. It stars Marine Vacth as a young woman named Chloé who discovers that her lover is concealing a part of his identity.

Chloé, a dowdy museum attendant suffering depression and abdominal pain, consults a gynaecologist. She is told that no physical cause can be found and what she needs is a psychiatrist. She consults Paul, under whose sympathetic care she smartens up her appearance and reacts more warmly to people. In fact they have fallen in love, and they move into an apartment together. Unpacking things, she finds that Paul has changed his name and hidden his family details from her.
