Saoirse Ronan has said that Ryan Gosling will be a "great" director because he is in tune with his work.
"I know he's going to be a great director because I've talked to him and I know his ideas," she said.
"He wrote the script, which is fantastic, and with each draft you can see it's really come on and you can see where he wants the story to go."
Saoirse, who is also continuing her successful streak with a leading role in Wes Anderson's upcoming film The Grand Budapest Hotel, is already a big fan of Ryan's work and the choices he has made in his career.
"I think you can tell by the choices he makes as an actor that he very much respects the story in the film and strong characters," she continued.
"He could have easily picked a bunch of blockbusters films over Blue Valentine and Drive but he didn't and because he's so great and was working with great people he made really great films and I think that's something that's important to him."
