A lot can change in two hours! Although the initial lineup for the 25th anniversary PaleyFest - akin to the TV version of Cannes, I like to say (as Ausiello rolls his eyes at me) - listed Sarah Michelle Gellar as yet to RSVP for the Buffy the Vampire Slayer reunion, Sunnydale's savior is now on board for the confab.

Other cast members repping the cult hit at the March 20 panel discussion include Amber Benson, Nicholas Brendon, Emma Caulfield, Eliza Dushku, Seth Green, James Marsters and Michelle Trachtenberg, as well as series creator Joss Whedon.
