"It's a football-themed show," explained Brad Ellis, a musical director on Glee (you know, the bearded guy with the glasses who plays piano and doesn't say anything?), in USA Today. "It's 500 extras," with cameos by "the USC marching band — the Trojan marching band. It's an enormous undertaking."
What else can Brad spill? For one, the "Thriller" mash-up is going to be huge. "Lots of dancers doing something very fun to watch them do, doing something really specific," he dished. "People that you don't expect to dance will dance."
And while production slowed due to a few Glee cast members coming down with winter bugs, that wasn't the only reason for the delay. "We also had fog roll in the day before just as we were about to begin filming." Doh! Despite these minor (albeit expensive) setbacks, we can expect the show to be epic.Source: USA Today
