WonderCon Anaheim's going out on a high note! FandomCharities.org and Whedonopolis.com, the folks who bring you the Buffy musical Once More with Feeling to close out San Diego Comic-Con, present a screening of Dr. Horrible's Sing-Along Blog! This will be an event to remember, so 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. Audience participation: it isn't just for Rocky Horror and mob riots anymore.
