John Noble On 'The Good Wife' And More TV Casting News

John Noble is heading to "The Good Wife."

The actor -- who recently finished his run as the beloved Walter Bishop on Fox's "Fringe" -- joins the CBS legal drama as a man from Alicia's (Julianna Margulies) past. He plays "a man that I have flashbacks [about]," Margulies told reporters, according to TV Guide Canada. "He’s a client that I used to take care of all the time ... He’s a very interesting character who is sort of a brilliant techie guy that constantly sues people."

Margulies added that Noble "elevated the part to such a different level." She added, "It was remarkable to work with him and just a pleasure to have on set," noting she was "blown away" by his talent.

Look for Noble in the 18th episode of "The Good Wife," which is expected to air in March. He joins an impressive list of "Good Wife" Season 4 guest stars: Maura Tierney, Stockard Channing, Matthew Perry, Amanda Peet, Kristin Chenoweth, Nathan Lane and Michael J. Fox.
