Of course this got my mind wondering....
Ejiofor as Frank N. Furter
Nate Fillion as Brad
Morena Baccarin as Janet
Alan Tudyk for the part of Riff Raff, which would mean
Gina Torres as Magenta
Sean Maher gets to put on the golden speedos and play Rocky
Eddie is played by Adam Baldwin
Jewell Staite gets the part of Columbia
and Summer Glau gets to play the Narrator.
