Wednesday Addams is joining a Monday drama. Christina Ricci has been tapped for a three-episode arc on TNT's Saving Grace (which premieres its second season tonight), says the Reporter.

Speed Racer's girlfriend will play a young detective who partners with Grace while Ham ( new TVGuide.com celebrity blogger Kenneth Johnson) takes a leave of absence.

Among her other TV creds, Ricci, of course, was most literally da bomb in a 2006 Grey's Anatomy stint. - Matt Mitovich
