Jude Law ascends the papacy as the fictional Pope Pius XIII, the youngest and the first American pope in history, in the new trailer for HBO and Sky Atlantic’s The Young Pope.

The 10-episode series hails from Paolo Sorrentino, who directed this year’s Oscar contender Youth. The story revolves around the new pope in the beginnings of his pontificate and the raucous he raises for claiming the title. Diane Keaton also stars as Sister Mary, an American nun living in the Vatican.

The Young Pope trailer is a hastened look at the pope getting ready to “wage a war without end” against his dissenters. “They chose a pope they didn’t know, and today they begin to understand,” he says.

Sorrentino said in a statement that the series is about “the clear signs of God’s existence. The clear signs of God’s absence. How faith can be searched for and lost. The greatness of holiness, so great as to be unbearable when you are fighting temptations and when all you can do is to yield to them. The inner struggle between the huge responsibility of the Head of the Catholic Church and the miseries of the simple man that fate (or the Holy Spirit) chose as Pontiff. Finally, how to handle and manipulate power in a state whose dogma and moral imperative is the renunciation of power and selfless love towards one’s neighbor.”

Silvio Orlando, Scott Shepherd, Cécile de France, Javier Cámara, Ludivine Sagnier, Toni Bertorelli, and James Cromwell fill out the cast for the series. As a joint effort between HBO, Sky, and Canal+, it will premiere overseas on Sky beginning Oct. 27 with a U.S. debut at a later time.
