Sooner or later our favorite TV shows all come to an end and the cast go their separate ways. If we’re lucky, our favorite performers return in new TV show and movie projects. Here’s where you’ll be able to see some of them…

Alex O’Loughlin, the star of CBS’ vampire drama, Moonlight, is returning to the network. This time, he’ll be playing a serial killer in an upcoming episode of Criminal Minds.

Anne Heche (Men in Trees) is giving television another try. She’s been signed to co-star in HBO’s new Hung series. It’s a dark comedy that centers on a well-endowed but struggling high school basketball coach named Ray (Thomas Jane). Heche will play his ex-wife, who has remarried.
