If you became hooked on James Norton when he was in Happy Valley tune in to the new series of Jerk where he is one of the big name signings for the third series starring Tim Renkow as a hapless anti-hero called Tim who has cerebral palsy and proves that even disabled people can behave like, erm, jerks. But a word of warning. Norton is playing a very different part here, with some very noteworthy and controversial scenes.
