Le Samourai
Several respondents highlighted this super stylish film about a laconic hitman who is framed for a murder and must find out who framed him and why.
La Haine
By far the most agreed upon movie in the comments. This film centers on three friends (one white, one black, one Arab) living in a low-income, mostly immigrant community suburb of Paris and was called “absolutely excellent” and “legit one of the best movies I've ever seen.”
Eyes Without a Face
A horror classic, Eyes Without a Face received surprisingly few mentions, though one of those commenters said the film is “bonkers and I love it.”
The Triplets of Belleville
A French movie without much French (or any language) spoken in it, The Triplets of Belleville received several mentions and compliments with one user calling it “fantastic.”
La Femme Nikita
Luc Besson is likely best known for his English-language film Leon: The Professional, but his French-language films deserve just as much attention. Especially La Femme Nikita, which follows a young woman who is trained to be an assassin.
Brotherhood of the Wolf
The film, which follows a pair of men who are sent to investigate the mysterious deaths in the town of Gévaudan, deftly combines horror and martial arts action in an 18th century period setting.
