Kenneth McMillan was an American actor. McMillan was usually cast as gruff, hostile and unfriendly characters due to his rough image. However, he was sometimes cast in some lighter comic roles that highlighted his gentler side. He was perhaps best known as Jack Doyle in Rhoda (1977–1978), and as Baron Vladimir Harkonnen in David Lynch's Dune.

The Pope of Greenwich Village is a 1984 American crime black comedy film directed by Stuart Rosenberg and starring Mickey Rourke, Eric Roberts, Daryl Hannah, Geraldine Page, Kenneth McMillan and Burt Young. Page was nominated for the Academy Award for Best Supporting Actress for her two-scene role. The film was adapted by screenwriter Vincent Patrick from his novel of the same name.
