WonderCon Anaheim is going out on a high note! Whedonopolis and FandomCharities.org, the folks who bring you the Buffy musical Once More With Feeling, to close out the San Diego Comic-Con, present an interactive screening of Dr. Horrible's Sing-Along Blog! Come and revel in the musical genius of The Whedons! But remember, the best part of the show is up to you! Cheer for Dr. Horrible! Cheer for Penny! Cheer for Moist! Cheer for the Freeze Ray! Cheer, or whatever, for "Captain Hammer, Corporate Tool!" Just have fun and be sure to make Bad Horse gleeful. There will be audience participation; it isn't just for Rocky Horror and mob riots anymore.
