It's Halloween. What's a Gleek to do? Let's put on The Rocky Horror Picture Show is what Will (Matthew Morrison decides to do!
The reason that New Directions is putting its spin on the 1975 cult classic (at least according to the plot) is that Emma's (Jayma Mays) a big fan and Will wants to impress Emma, so... it's time for "Time Warp."
That's Kurt (Chris Colfer) underneath the bald Riff-Raff wig, by the way. Movie alums Barry Bostwick and Meat Loaf are in the guest cast, playing station managers at the TV station where Sue Sylvester (Jane Lynch) hurls her "As Sue Sees It" darts. And, yes, Sue's scheming to stop the show.
The Halloween-themed episode will be broadcast tonight at 8:00 pm (ET) on FOX.
