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 demeanor.
McMillan made his film debut at age 41 with a small role in Sidney Lumet's gritty police drama Serpico. The actor played a borough commander in The Taking of Pelham One Two Three, but often was cast as characters who were less than heroic, such as a cowardly small town sheriff in Tobe Hooper's 1979 TV mini-series Salem's Lot, a similar law enforcement officer in the 1987 Burt Reynolds film Malone, William Hurt's bitter paraplegic father in Eyewitness, a wily safe cracker in The Pope of Greenwich Village and a racist fire chief in Ragtime who is memorably told off by the New York police commissioner, James Cagney.
He portrayed the vile and grotesquely obese Baron Vladimir Harkonnen in Dune, the pathetic drunken pop of Aidan Quinn in Reckless and a sleazy high roller gambler in "The Ledge," an episode of the horror anthology film Cat's Eye. Yet he did sometimes end up on the right side of the law, playing Robert Duvall's detective partner in True Confessions and a judge who must rule whether Richard Dreyfuss has the right to die in Whose Life Is It Anyway?.
McMillan was also adept at comedy, giving especially funny and engaging performances as a baseball club manager in Blue Skies Again, Meg Ryan's corrupt security guard captain dad in Armed and Dangerous and a dotty senile veterinarian in Three Fugitives.
McMillan had a recurring role as Valerie Harper's irate boss Jack Doyle on the TV sitcom Rhoda. Among the TV shows McMillan did guest spots on are Dark Shadows, Ryan's Hope, as a 53rd precinct lieutenant on Kojak, Starsky and Hutch, The Rockford Files, Moonlighting, Magnum, P.I., and Murder, She Wrote.
Outside of his film and TV credits, McMillan also frequently performed on stage at the New York Shakespeare Festival. He acted in the original Broadway productions of Streamers and American Buffalo. He won an Obie for his performance in the Off-Broadway play Weekends and Other People.
McMillan died of liver disease at age 56.
