If the BBC says it, it's gotta be true!
Here are my casting suggestions:
Riff Raff – Johnny Depp
Columbia – Angelina Jolie
Magenta – Catherine Zeta-Jones
Brad – Leonardo di Caprio
Janet – Scarlett Johannsen
Eddie – Andrew Dice Clay
A Noted Criminologist – Michael Caine
But who will play Dr. Frank N. Furter, Tim Curry's part in the original?
Got it! John Travolta!
