Luck of the Irish - Saoirse Ronan stars in Ryan Gosling's first movie behind the lenses
SAOIRSE Ronan is the star of Ryan Gosling's directoral debut which will preview at Cannes Film Festival.
Entitled How to Catch a Monster, it sees the Oscar-nominee (20) taking on the role of the girl-next-door in the fantasy-noir.
She's expected to be cutting a dash at the red-carpet premiere of the movie next month, with the festival starting on May 15.
Taking on the role of director, Gosling (inset) filmed the movie in Detroit last May and was joined by a star-studded cast including Christina Hendricks, Matt Smith and Eva Mendes.
Speaking about her role, Saoirse (far right) said she plays a girl called Rat because she "kind of lives like a rat".
"She lives in this house with her grandmother and her grandmother's a hoarder and there's lots of man-made tunnels within the house because there's so much memorabilia that the grandmother's collected over the years," she said.
"And I had a pet rat, Nick."
She told how Hollywood hunk Gosling hired a dream expert called Greta to help them get into character.
She had the actors write themselves letters each night and then come in the next day to discuss them.
"I'd tell Greta, 'Listen, I don't know what this is, but I was doing this last night, and then this person popped up and she'd make sense out of it. And that was our rehearsal'," said Saoirse.
Sharing their dreams helped them bond as a cast, she said.
"It made us become very close," she added.
"It was a very new method for me, because all of a sudden Ryan was encouraging us to incorporate our own personalities into our characters -- how you feel about things, what your anxieties are, and things like that."
