Children of Men. Easily Cuaron's best film. Forgot what a great supporting cast it had. Hadn't watched it in quite a while.
Also recently watched 'We Need To Talk About Kevin' for the 2nd time. The film is utterly astonishing. One of the most powerful dramas ever put to film. An absolute masterpiece. Tilda Swinton and Ezra Miller are utterly spellbinding in it.
