Prime Video Streams Binge-Worthy Miniseries Starring Diane Keaton
Diane Keaton’s career stretched across five decades. Many remember her as Kay Adams-Corleone in The Godfather (1972), a role that marked her breakthrough. She later appeared in The Godfather Saga and many other series. Yet one project remains especially memorable to audiences — The Young Pope, a striking 2016 HBO miniseries, now streaming on Prime Video, that once drew people in with its strange beauty and quiet strength.
We are deeply saddened by the loss of the wonderful Diane Keaton.
We had the privilege of working with her on Paolo Sorrentino’s The Young Pope. Her talent and dedication inspired us all.
Our heartfelt condolences go out to Diane’s friends and family.

The Young Pope Story
Diane Keaton plays Sister Mary, the nun who raised the newly elected Pope, Lenny Belardo, played by Jude Law. He is a young American cardinal who has been suddenly chosen to lead the Church. His reign begins with secrecy and control, pulling away from the public eye as he rewrites the rules of power inside the Vatican.
Sister Mary becomes both his guide and his conscience. Their connection adds a quiet weight to the story, while the walls of the Vatican tremble with ambition and faith.
