With cheap but entertaining special effects as a meta-commentary on Derkholm's own cheap but entertaining special effects?

Anything to do with the tour could be cheap but entertaining, of course, but there's still griffins, dragons, demons and all that other stuff that needs to be awesome for real.

I also think you could do a lot of awesomely creepy and atmospheric stuff with a film of Black Maria . . . though from what I understand there is already a ballet?(!?!?!?!)

Hee! OMG, what I wouldn't pay to see that ballet. Yes, Black Maria would be pretty great, demanding less money though still quite a lot of talent.
