Here's a trio of TV casting updates for you. First off, we already know that Lisa Edelstein will not be reprising her role as Dean of Medicine at Princeton-Plainsboro on the upcoming eighth season of House M.D. but the female portion of the cast won't be down one as EW has learned that Knocked Up and Paper Heart star Charlyne Yi will become a series regular this fall. She'll be playing another young doctor joining House's team, and with her awkward nature and charming comedic timing, it should be quite an interesting match-up with Hugh Laurie.

Details on casting for Parks & Recreation and HBO's new comedy series 40 can be found after the jump.

While we normally don't see his face on TV due to his voice work on The Simpsons, Dan Castellaneta (the voice of Homer Simpson, amongst other characters in Springfield) will be heading to Pawnee, Indiana for a guest spot on Parks & Recreation. Vulture says he'll play an NPR-like talk-show host and I'm betting he'll likely end up interviewing Amy Poehler's character at some point. Too bad a real-life version of Mayor Quimby can't show up on the show too.

Finally, Deadline has word that Michael Rapaport (Prison Break) will join Entourage creator Doug Ellin's new comedy series 40 set up at HBO. Ed Burns is already starring in the ensemble comedy which follows four lifelong friends who help each other navigate life at 40, which isn't all they expected it to be. Sounds like it's going to be an expanded, pay-cable version of Men of a Certain Age which I was sad to see get cancelled after two great seasons. Burns plays a married guy and a father who used to work at Bear Stearns making over $2 million a year but has now been out of work for almost a year. Meanwhile Rapaport will play another married man described as a neurotic everyman. It'll be interesting to see if this new series can measure up to the success of Entourage.
