Christopher Walken is one of the most unique character actors of all time. Walken is renowned for his idiosyncratic mannerisms and has reinvented himself for audiences of many different generations. He has attracted some younger viewers with his frequent appearances on "Saturday Night Live" and Fatboy Slim's infamous "Weapon of Choice" music video.

Although Walken is largely associated with his comedic roles, he has delivered many riveting dramatic performances. At 79, Walken hasn't shown any signs that he is slowing down. He has recently found success on television with his roles as Burt Goodman on Apple TV+'s acclaimed science fiction series "Severance" and Frank Sheldon on Amazon Prime Video's crime series "The Outlaws." It was recently announced that Walken will be joining the cast of "Dune: Part Two" as Emperor Shaddam IV. It will be exciting to see Timothée Chalamet's Paul Atreides face off against the most fearsome antagonist in the "Dune" universe.
