On the pretext of seeing if he's alright Mary-Jane takes Julien to a café where he plays his favourite arcade game, Kung Fu Master.

conceived of the film while Agnès Varda was filming her for the documentary Jane B. par Agnès V. Most of the cast were taken from Birkin and Varda's family, with Birkin's real life daughters and parents playing her daughters and parents in the film. Charlotte Gainsbourg later admitted to disliking both the filming of Jane B. par Agnès V. and Kung Fu Master as Varda and her film crew remained camped in her home for a year in order to complete the projects.
Reception and release
In 2015, both Kung Fu Master and Jane B. par Agnès V. were acquired for U.S. distribution by Cinelicious Pics. The films enjoyed a brief theatrical re-release before being streamed on the movie streaming service Fandor. Varda expressed frustration at the film's limited release saying "I can get the Palme d’Or, but I can’t get exhibition, so it’s a contradiction."
