The actress will play a matchmaker who becomes a love interest for the title radio psychiatrist played by Kelsey Grammer. The multi-Emmy Award-winning series (a "Cheers" spin-off) recently announced it will end its 11-year run on the network. Linney, who is currently winning praise for her turn in the film "Mystic River," earned a Tony Award nomination for her last Broadway role in The Crucible opposite Liam Neeson. She has also appeared on stage in Uncle Vanya, Honour, Holiday, Hedda Gabler and The Seagull. Her film credits include Kenneth Lonergan's "You Can Count on Me," the HBO version of "The Laramie Project," and the upcoming film "Kinsey" (once again opposite Neeson) penned and directed by "Chicago" screenwriter Bill Condon.

"Frasier" stars Grammer as Frasier Crane — the role he made famous on "Cheers." The sitcom, which also stars David Hyde Pierce, John Mahoney, Jane Leeves and Peri Gilpin, airs Tuesdays on NBC at 9 PM ET (Check your local listings). Broadway's Bebe Neuwirth (Chicago, Damn Yankees) occasionally makes guest appearances reprising her "Cheers" role as the doctor's ex-wife.
