John Voight as Pope? C'mon.
From Midnight Cowboy to Pope! What a career arc!! (Seriously, no one knows Voight anymore except as being Angelina Jolie's father.)
Cary Elwes first became famous for his role as Westley/The Dread Pirate Roberts in "The Princess Bride" (1987).
Jon Voight plays Pope John Paul II in his later years.
