The beautifully realized Oscar-nominated romantic drama Brooklyn, adapted from Colm Tóibín’s book of the same name, has a moving and thought-provoking ending. Saoirse Ronan stars in the adaptation as Eilis Lacey, a young Irish woman who emigrates to Brooklyn in the 1950s. While caught between two homes, Eilis finds herself in a love triangle with Tony (Emory Cohen), an Italian-American plumber in New York, and Jim (Domhnall Gleeson), a well-off suitor back in her hometown of Enniscorthy. Brooklyn was nominated for three Academy Awards – Best Picture, Best Actress (for Ronan), and Best Adapted Screenplay – but sadly, in spite of its universal praise, it didn’t win any.
