Anne Dudek to Star in Covert Affairs With Piper Perabo and Lewis Black to Guest on The Big Bang Theory

Fall TV is almost here, and I'm pumped to greet my favorite shows again. Part of the fun is seeing the new faces that come along, and today there's a batch of newcomers to meet.

• The Daily Show's Lewis Black will make an appearance on The Big Bang Theory as a professor who's down on his luck. He'll only be on one episode — the second of the season — but I'm guessing it will be a memorable moment for the CBS sitcom.
• Joe Morton will also be playing a professor next season, but he'll be heading to Brothers & Sisters. Morton has signed on for a recurring role as Justin Walker's anatomy teacher in med school. It sounds like he'll be a mentor type, but friendships don't stay scandal-free for long when it comes to the Walkers.
• Anne Dudek will play Piper Perabo's sister on the new USA spy series Covert Affairs.Yay! I've been rooting for her for what feels like forever, since I still think she deserves an Emmy and completely made some of my favorite TV episodes. I'm glad to see she's found a new TV home, though I still would love to see her get a lead role.
