Kenneth McMillan (July 2, 1932 – January 8, 1989) 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 Harkonnen in David Lynch's Dune.
