 Buffy sing @-@ alongs received growing media attention as they spread . At the 2007 Los Angeles Film Festival , a special screening and sing @-@ along was held that featured both Marti Noxon and Joss Whedon giving brief speeches to the audience . In October 2007 , after a dispute with the Screen Actors Guild over unpaid residuals , 20th Century Fox pulled the licensing for public screenings of " Once More , with Feeling " , effectively ending official Buffy sing @-@ alongs . Whedon called the cancellation " hugely depressing " and attempted to influence the studio to allow future showings .
