Kristen Stewart joined Imogen Poots for a special screening of their movie The Chronology Of Water at White City House in London on Saturday.

The pair beamed for photos and could be seen laughing on stage during an interview with Briony Hanson, the British Council's Director of Film.

Imogen, 36, looked incredibly chic in a brown lace top and suede midi skirt, while Kristen, 35, cut a casual display in a burnt orange jacket. 

A few friends joined the pair for their event including Ted Lasso star Brett Goldstein, 45. 

The movie has received lots of praise by critics as it focuses on difficult topics, such as childhood trauma and addiction. 

Earlier this month, Kristen accepted the Rising Star Director Award at the SCAD Savannah Film Festival for her directorial debut.

The Chronology of Water, which she also co-produced and adapted for the screen from the visceral 2011 memoir by American swimmer Lidia Yuknavitch.

Imogen stars as Lidia in the heartfelt drama, which tells her story about becoming a competitive swimmer after surviving an abusive childhood.

Rounding out the talented cast for the drama are Jim Belushi, Tom Sturridge, Thora Birch and Sonic Youth rock band's Kim Gordon.

Kirsten first presented the film at Cannes Film Festival earlier in May, where the film was met with critical acclaim and a standing ovation.

Variety called it 'a stirring drama of abuse and salvation, told with poetic passion', while Indiewire critic David Ehrlich said 'there isn't a single millisecond of this movie that doesn't bristle with the raw energy of an artist'. 

Following the Cannes premiere, Kristen opened up about her passion to tell Lidia's story, telling AFP: 'I had just never read a book like that that is screaming out to be a movie, that needs to be moving, that needs to be a living thing.

She gushed how it was awe-inspiring how Lidia was 'able to take really ugly things, process them, and put out something that you can live with, something that actually has joy.

'The reason I really wanted to make the movie is because I thought it was hilarious in such a giddy and excited way, like we were telling secrets. I think the book is a total lifeboat.

It certainly saved Lidia and made her a cult writer, with her viral TED Talk The Beauty of Being a Misfit, inspiring a spin-off book, The Misfit's Manifesto.

Kristen told AFP: 'Being a woman is a really violent experience. Even if you don't have the sort of extreme experience that we depict in the film or that Lidia endured and came out of beautifully'.

The Twilight star insisted there were no autobiographical parallels per se that drew her to the original book.

She explained: 'I didn't have to do a bunch of research. I'm a female body that's been walking around for 35 years. Look at the world that we live in.

'I don't have to have been abused by my dad to understand what it is like to be taken from, to have my voice stifled, and to not trust myself. It takes a lot of years (for that) to go. I think that this movie resonates with anyone who is open and bleeding, which is 50 percent of the population.'

Kristen told reporters she was never really tempted to play Lidia herself before deciding to cast Imogen, who she called 'the best actress of our generation'.
