Him (2021)

Sadly not based on the narrative of the Rupert Holmes Top 40 hit from 1979, Him (2021), or Lui, is a French flick written, directed by, and starring Guillaume Canet as the title character. He's married to Virginie Efira's unnamed spouse, carrying on an affair with Laetitia Casta's unnamed mistress, and suspicious that his own wife might be carrying on with his friend Mathieu Kassovitz. We get why this dude wrote this movie, a sex scene with the incredible Laetitia Casta seems like a good enough reason, but he also gets cucked too his face by Virginie Efira as he imagines his buddy banging her on the couch!
