Penelope Ann Miller, late of Fox’s Vanished and a bunch of other stuff, is joining TNT’s forthcoming midlife crisis drama Men of a Certain Age as the ex-wife of Ray Romano’s neurotic party-supply store owner, sources confirm to me exclusively.

Miller is committed to appearing in at least five episodes of Men, which bows in December and stars Andre Braugher, Scott Bakula, and Romano as a group of friends getting old approaching midlife together.
