If you're looking for a typical movie India Song is definitely not for you. The highly experimental movie is both long and smashes a lot of the rules for conventional cinema. It teaches YOU how to watch IT.
The plot, such as it is, is about the wife of a French Ambassador living in Calcutta. Bored she engages in a series of love affairs. This information is provided completely in narration that plays over a series of ghost like images in which we see the ambassador's wife dance and walk and flirt with a handful of other people in a mostly empty and abandoned looking mansion. It's essentially a ghost story.
I have nothing against slow films or unconventional ones but this simply wasn't for me. Delphine Seyrig acts out the part of Anne- Marie Stretter, the wife, but watching her I was reminded of that OTHER famous movie she did in 1975, also experimental and unconventional and also directed by a woman who was a cinematic powerhouse: Chantal Akerman. In terms of plot there's not a lot to tie Chantal Akerman's Jeanne Dielmann to Marguerite Duras' India Song, but the two feature a similar style of long shots and repetition. That said I find Jeanne Dielmann by far the easier of the two to watch. While that movie is hypnotizing and entrancing Duras' movie feels stale, like a book of hers that was never quite able to come to fruition.
A movie that perhaps only Duras devotees or Seyrig fans will love.
