Glee fans have been eagerly anticipated the Rocky Horror-themed episode of the show, which will air just before Halloween. For weeks, the cast and the fans have been speculating about which actors will play which roles - and we�ve finally got some answers thanks to a new photo gallery. Follow the jump to get a sneak peek!

Newcomer Chord Overstreet will get the role of Rocky. Frankly, we should have seen this coming. Blonde and gorgeous, Chord is the perfect choice for this one.

Further pictures reveal that John Stamos will take over as Eddie, Chris Colfer will don a skin cap to become Riff Raff and Dianna Agron will dress up like Magenta. In the picture above, Cory Monteith looks like he�ll make a great Brad. We can only assume that Lea Michele will play Brad�s love interest Janet�and maybe Kevin McHale, with his glasses and wheelchair, will sit in as a the scientist?

The pictures leave one key role to speculation: that of Dr. Frank-N-Furter, who dons a tiny leather and fishnet outfit when first introduced in the classic film. Reportedly, the male Glee cast members have been very worried about who will have to wear the famous look. View the entire Glee-goes-Rocky picture gallery on Perez Hilton’s blog.
