The highly anticipated series takes place thousands of years before the events of the beloved 2000s film franchise, but that doesn't mean there won't be familiar names and faces. Whether audiences are newcomers to The Lord of the Rings or Silmarillion scholars, chances are they will recognize a number of The Rings of Power's denizens from their appearances in other massive fantasy and sci-fi franchises.
Peter Mullan is a veteran actor with many iconic performances under his belt. In The Rings of Power, he appears as the legendary Dwarven King Durin III, wielder of one of the titular rings of power.
Eagle-eyed fans may look beyond the Dwarven beard and prosthetics to recognize him as Westworld's James Delos. The Delos family patriarch was the original creator of the android-staffed theme park. Mullan's terminally ill Delos was determined to use the park to unlock the secrets of his own immortality.
