Memorable ”Will & Grace” guest stars: Michael Douglas

Douglas throws himself with gusto into the role of Gavin, a newly out cop who invents an elaborate ruse to get closer to Will. But Jack, acquainted with Gavin from a support group, knows his secrets, including his phobic disgust for people with food stuck in their teeth. His slow-dance with Will makes for a wonderfully touching sight gag. For being so game in this 2002 episode, Douglas earned an Emmy nomination.
