Gerard Kelly
Lots of praise has (deservedly) been heaped on the two leads and, of course, the director who can't put a foot wrong, but I thought Gerard Kelly stole the show with his one scene as the parish priest.
He had a kind of *beep* you' swagger about him and the venom with which he blasted Roison was one of the most powerful moments in the film. Great performance! Even if it lasted just a couple of minutes...
