Jane B. par Agnès V. is a 1988 French docu-drama directed by Agnès Varda and starring French-English actress Jane Birkin. The film was conceived when Birkin admitted to Varda she was apprehensive about turning 40 and Varda told her it was a beautiful age and the perfect time to make a portrait on Birkin's life.
The film mixes interviews with Birkin about her past and current life with small vignettes where she takes on roles that either she or Varda are interested in seeing her play.
