The devilish Aiden Gillen—a familiar face in the UK, but best known here for recurring roles on HBO’s The Wire and Game of Thrones—gives a sensitive performance as a low-rent photographer in North London still grieving over the hit-and-run death of his teenage son a year earlier. His glancing friendship with a schoolboy whose brother has just been killed in a gang altercation invites mounting harassment from the young punks who committed the crime, yet the photographer’s feelings for his dead son inhibit him from taking action against the boys. This debut feature from writer-director Simon Blake shows great promise, though it’s rather an odd bird, veering between intelligent, insightful chamber drama and Death Wish histrionics (the climax is especially overheated). Amanda Mealing contributes a fine performance as the hero’s estranged wife; her scenes with Gillen are the movie’s high point.
