Kristen Stewart has been making a big splash at this years Cannes Film Festival with the premiere of her directorial debut, The Chronology of Water. Shes spoken about the film and her desire to make it many times over the years, but now that its done (sort of), Stewart has been sharing far more about the chaotic journey she took to get here.Heres what we know!1. Its based on Lidia Yuknavitchs memoir.Imogen Poots stars as Yuknavitch, a "lifelong swimmer turned artist." The memoir takes a hard look at gender, sexuality, violence, grief, and addiction through a non-linear lens, with Stewarts film promising to do the same, though allegedly taking major deviations from the source material."Its just about how the things that happen to us live in our bodies and how we excavate, recreate, reframe things in order to survive," she told Vulture. "And also to define ourselves."2. Stewart herself has a hard time describing the film.If the description above sounds vague and broad all at once, its because the story itself encompasses so much."People say, 'Whats the movie about?' and Im like, 'Oh fuck, I dont know life?'" Stewart said while speaking at a Breaking Through the Lens event. "Its about being in love. Its about losing people. Its about your parents fucking you up. Its about writing. Its about making art. Its about how memory works. Its about the ocean. Its about the body. Its about hating the body. Its about loving the body. Its about desire. And its also just this vibe."3. She sent Fiona Apple a letter asking to use her music.Stewart has mentioned a few times now that she was so desperate to use Fiona Apples songs in her movie that she wrote her a letter despite the two having never met."I think I said, 'Whats yours is mine now,'" she recalled during her interview with Vulture. "Like, 'I know that these are your songs, but theyre fucking mine. They belong to me, they really belong to this movie, and can we please show that?'"4. It took her eight years to get it made.See on InstagramKStew fans have been listening to her talk about The Chronology of Water for nearly a decade now. She was determined to make this her directorial debut, even threatening to stop acting until she was able to make it happen.5. She was working on it up until five minutes before the premiere.Stewart told the Cannes audience that she finished the movie "five minutes before" but even that isnt quite the truth. She later told Vulture that they werent merely tweaking edits, but were and are actually still working on completing the film.6. She says Imogen Poots has "Big Tit Energy."Asked why she cast Poots in the lead rather than tackling the role herself, Stewart replied, "She doesnt have big tits or anything, but she seems like she does.""She has Big Tit Energy. Its like Big Dick Energy she has BTE," she continued. "I was like, I just feel like you have these big tits and you just have to play this part."7. She got tattoos to commemorate her experience on the film.Stewart has mentioned two tattoos she got related to the film one on her arm that says "Why," and one on her thigh that says "MINE.""The coolest song in the movie is when she comes on her hand, smells it, wipes it on her fucking bicep, and goes, 'I didnt know a girl body could do that. Shoot come," she explained. "And then this song comes on and it goes, 'Mine, mine, mine, mine.' And its just fucking mine."8. Shes likened the films pacing to that of a female orgasm.Forget the "three-act success story" that film audiences are accustomed to, Stewart says. The Chronology of Water currently has a run time of 2 hours and 8 minutes, because "its a serious fucking movie" that she believes deserves to take up that space."Its like a female orgasm. Its like, 'Almost, almost, almost. Stick with me, stick with me, stick with me!'" she said, adding, "I dont think the movie is long."As for when the rest of us will finally get to see Stewart's long-awaited directorial debut, that has yet to be determined. But we've waited eight years already we can wait a little longer.
