After Blythe Danner and Swoosie Kurtz made a memorable turn as Peter Facinelli’s lesbian moms on the first season of Nurse Jackie, the show’s producers decided to bring the characters back for another guest stint in the upcoming third season. However, Danner was unavailable because she is shooting a movie, so Judith Light was tapped for the role… Robert Knepper is adding to the string of bad guys he’s played on TV, most notably on Prison Break and Heroes. In a 2-episode arc on Showtime’s upcoming drama Shameless, he will play a goon who is chasing William Macy’s alcoholic partiarch character because of a scam they had going together.
