The 26-year-old actress plays Maureen, an American in Paris trying to make contact with her recently-deceased twin brother, in her latest movie and though she herself has experienced sleepless nights in the past, she admits she has never had it as tough as her character.

Kristen - who is alone in many scenes in the movie - said: "I was really scared of this movie.

"[Maureen] is just the most lonely person I've ever played. I've had some spiral periods where the unanswerable questions keep you up at night to a vaguely debilitating degree, but nothing like this girl."

Despite the gruelling schedule of making the film, Kristen enjoyed the experience because director Olivier Assayas allowed her a lot of freedom and valued her input on the production.

She told Entertainment Weekly: "I'm used to directors really knowing what they want to say and making sure those concepts are displayed by the actors. In this case, all Olivier wants to do is ask you questions and see you flop around and figure them out. It's really cool."

And the filmmaker - who previously worked with the actress on 'Clouds of Sils Maria' - credits his leading lady for making the finished work what it is.

He said: "This film in many ways belongs to Kristen. I was directing it from the outside, but she was directing it from within."

The blonde beauty recently moved into directing, with a music video and short film 'Come Swim' to her name, and she loves the feeling of having an entire project of her own.

She said: "It's so amazing to have something that exists because you protected it and invested in it all the way to the end.

"I don't think there's a huge separation from acting and directing for me.

"I come at it with the same intention. I'm pretty obsessed with the process of how things are put together."
