Kate Walsh has had a bit of a roller-coaster ride in her time on "Grey's Anatomy," acting her way through a couple of love triangles, numerous medical crises and, currently, a bout of unresolved romantic tension with one of her interns.
All the ups and downs could, however, have a pretty big payoff for the actress: her own show.
ABC and "Grey's Anatomy" creator are considering a spinoff of the show that would focus on Walsh's character, neonatal surgeon Addison Montgomery. The network isn't commenting, but The Wall Street Journal reports that Rhimes is working on an idea to spin off Addison.
The details of that idea are scant at the moment; the Journal says Rhimes has yet to settle on plot details such as whether Addison would leave Seattle. She is, however, planning a May sweeps episode that would focus on Addison and serve as a back-door pilot for the new show.
Should that happen, it would likely push another Rhimes project, about a group of female journalists in New York, on to the back burner.
Character-based spinoffs are hardly a lock to succeed -- for every "Frasier" there's at least one "Joey" -- but a show born of "Grey's Anatomy" would probably have a better chance than most. The draws 20 million viewers per week, and only "American Idol" has better ratings in the adults 18-49 demographic that advertisers covet.
Walsh joined "Grey's Anatomy" in the show's first-season finale, becoming the third side of a love triangle also involving her TV husband, Dr. Derek Shepherd (Patrick Dempsey) and Seattle Grace intern Meredith Grey (Ellen Pompeo). She became a regular midway through last season.
Her credits also include "Under the Tuscan Sun," "The Drew Carey Show" and "Kicking & Screaming."
