Some casting updates from EW's Michael Ausiello:
- Balthazar Getty ("Brothers & Sisters") will guest star on an upcoming episode of "Medium", to be directed by Patricia Arquette. He will play a wealthy real estate magnate whose wife goes missing.
- Hector Elizondo and Amy Madigan are both set to return to "Grey's Anatomy" during this season. Madigan reprises the role as the on-call psychiatrist, this time with another doctor sitting in, and Elizondo returns as Callie's dad, who is pretty shocked about the girl-loving side of her daughter.
- Marilu Henner will also show up in the "ER" finale, as a mother-of-the-groom, whose evildoings land both her and her future daughter-in-law in the hospital on the wedding day.
Additionally, Mike reports that Ashley Jensen will exit "Ugly Betty" at the end of this season. At least as a regular. The occasional guest appearance is still an option for future seasons.
