Olivier Assayas and Kristen Stewart: Watch a Free Documentary About Their Collaboration on ‘Personal Shopper’
Here's the link to a very nice write up from IndieWire's senior film critic David Ehrlich where he discusses a 75-minute documentary on Assayas career as a director: https://www.indiewire.com/2018/09/olivier-assayas-personal-shopper-documentary-aware-anywhere-1202007783/
Near the end of the article is a link to this documentary which will be available to stream free of charge for a limited time. It contains the most extensive behind-the-scenes and B-roll footage I have ever seen of Personal Shopper. Boy do I wish this footage was included in the Criterion Collection Blu-ray of this film, which has an awesome Blu-ray transfer BTW.
Olivier Assayas often publicly praises Kristen for her talent as an actress, so I particularly love the part where he also speaks very highly of Kristen's directing abilities, mentioning how he would set up the shots and direct the cast from the film script while Kristen would be the one who dictated the duration of the shots and manner and direction in which she would move in space @39:25 in this video. A very good example showing how Kristen envisions a particular scene as a director can be found @54:55-57:25 mark. So their collaboration, according to Assayas himself, wasn't merely between that of a director and his lead actor, but rather a joint effort between a director and his lead actor/co-director, Kristen Stewart.
After watching this documentary, I kinda wished Assayas would have included more of the B-reel footage which didn't make the final cut in the film, such as @45:05, which is one of the most adorable on-set shots of Kristen that I can recall offhand. Perhaps Assayas didn't add this clip as it would've detracted from the overall seriousness of the film.
