The Paley Center for Media will present panels for Joss Whedon’s Dollhouse (Fox) and Dr. Horrible’s Sing-Along Blog at this year’s twenty-sixth annual William S. Paley Television Festival (PaleyFest09).

Joss Whedon, Nathan Fillion, Zack Whedon, Felicia Day and Jed Whedon are confirmed.  Additional members of the cast and creative team from both series will be announced shortly.

The dates haven’t been cast in stone yet (an unnamed W source says The Paley Center is hoping to have the evenings run consecutively).

The complete schedule for PaleyFest09 will be announced on Wednesday, February 18, 2009. The two Joss Whedon projects join the previously announced Fringe (Fox) and True Blood (HBO) atthis year’s Festival.

Returning to the historic Cinerama Dome at the ArcLight Cinemas in Hollywood, PaleyFest09 will be held from April 10 to 23, 2009.

Special Premium and Garanteed ticket packages will be sold so keep checking for updates at the official PaleyFest website.
