My earliest childhood memory of McMillan onscreen is of watching him countless times in the memorable "The Ledge" episode in Lewis Teague's Cat's Eye. This guy is just so damned pleased with himself after he captures his wife's lover (Robert Hays) and makes the pretty boy walk around the ledge of his Atlantic City high-rise. Who can forget McMillan cackling and howling while jumping up and down on his bed in a satin robe? I sure as hell can't!
As a kid, I'm pretty sure I had this action figure of his character from Dune:
So, obviously, as evidenced by Dune, Cat's Eye, Ragtime, and other roles, it was easy for filmmakers to use his physique and facial features for villainous parts or as cops, but my favorites remain those that utilized his working class, New York Irish persona: Bloodbrothers, as a paralyzed bar owner who shares a heartbreaking scene with co-star Paul Sorvino, Reckless, as Aidan Quinn's hard-boozing old man, Eyewitness, as Bill Hurt's paralyzed pop, and, most especially, Chilly Scenes of Winter, in which he plays Gloria Grahame's loving husband and stepfather to John Heard. Heard is hard on the guy, but eventually McMillan's old softie is able to crack Heard's exterior as symbolized by the young man's acceptance of his gift of Turtle Wax. I've missed McMillan's high-pitched, New York-accented voice on screen for the last couple decades, but I'm thankful the actor was so busy during his two decades of performing, leaving behind plenty that I still have not seen.
McMillan almost has as much screen time in this trailer for Blue Skies Again as star Robyn Barto and Obscure One-Sheet sure is thrilled about that:
After all of the Stephen King cinematic references, watch McMillan chew scenery at the expense of Robert Hays and the titular cat:
