A Faithful Man is a French romantic-comedy film directed by Louis Garrel. The movie centers around a love triangle involving Marianne (Laetitia Casta), Abel (Louis Garrel), and Paul (played by filmmaker and actor, Lily-Rose Depp's father, Johnny Depp).
Marianne is dating Abel when she unexpectedly falls pregnant with Paul's child. She decides to leave Abel and start a new life with Paul. The film then jumps ahead eight years to Paul's sudden death, which prompts Marianne to return to Abel.
Initially, things seem to be going smoothly as Abel and Marianne rekindle their relationship. However, Abel soon discovers that Marianne has cheated on him with several other men during her time with Paul. This revelation causes Abel to become jealous and insecure about Marianne's love for him.
Complicating matters further is the presence of Paul's young son, Joseph (played by Garrel's real-life son, Joseph Garrel). Abel and Marianne must navigate their new relationship while taking on the responsibility of raising a child who is not Abel's biological son.
The movie explores themes of love, jealousy, fidelity, and the complexities of romantic relationships. It was released in France in 2018 and received positive reviews from critics who praised the film's witty dialogue and charming performances.
