Saorise Ronan has said she is thrilled with the gathering Oscar buzz for Brooklyn, the film adaptation of Colm Tóibin's novel which also stars Domhnall Gleeson and Emory Cohen.

Speaking on The Late Late Show on Friday night, Ronan, who was previously nominated for a Best Actress Oscar for Atonement when she was 13, also sounded a note of caution about expectations when award season comes around.

"It is nice and it is lovely," she said. "But the good thing about having that sort of discussion around it now, touch wood, is that when you've been on both sides of it and had both perspectives, it's great and everything works out well when it comes to buzz but then nothing comes of it but the film is still great and you love it. The talk of an Oscar has helped me realise all the elements that go into that whole world."

Directed by Intermission director John Crowley with a screenplay by author Nick Hornby, Brooklyn has been attracting rave reviews.

The 1950s romance is set in Ireland and New York City and sees Ronan's character, Eilis Lacey, immigrate to Brooklyn. After falling for an Italian American man (Emory Cohen), she is forced to consider a move back to Ireland after learning of some devastating news and a complicated love triangle quickly develops.

Brooklyn is due for release here on November 6.
