Second episode in this brand new eight-part HBO series which follows the story of a fictional American-born pope played by Jude Law. It also stars the legend that is Diane Keaton in what is her first regular role for TV, - playing a nun that works alongside the pope. In tonight's episode, concerns mount within the Vatican as the newly elected - and distinctly radical - Pope Pius XIII prepares to make his inaugural speech to the faithful at St Peter's Square.
