I was too distracted to watch when this French teaser for Michel Hazanavicius’s Redoubtable, which will debut at the Cannes Film Festival, appeared online last month. Set in the mid ’60s, the film is about a love affair between legendary nouvelle vague director Jean-Luc Godard and Au Hasard Balthazar and Weekend star Anne Wiazemsky. But what gets me here is Louis Garrel‘s channeling of Godard, particularly the low-key insouciance.

The film, which Godard has allegedly described as “a stupid idea”, is based on Wiazemsky’s writings about her Godard relationship, which began when she was in her late teens. Born in 1930, Godard was 17 years older than Wiazemsky. He wound up casting her in La Chinoise (’67), Weekend (’67) and One Plus One (’68). They were married between ’67 and ’79.

It’s been reported that Wiazemsky was 17 when her affair with Godard began. I’m figuring more like 19. She was born in ’47, and was 18 when Au Hasard, Balthazar (released on 5.25.66) was shot in the summer or fall of ’65. In her book “Jeune Fille” Wiazemsky wrote that Bresson was obsessed with her and never let her out of her sight, so it seems unlikely that Godard was circling her then. The timetable indicates that the Godard coupling began in late ’65 or ’66.

26 year-old Stacy Martin, whose last high-profile role was in Part One of Lars Von Trier‘s Nymphomaniac, plays Wiazemsky. Berenice Bejo (The Artist) costars.
