And the answer is...

I seem to have done it again. Agree to set another sf quiz that is. The thing about setting a quiz is that after a certain point it does not really get any easier with practice. It gets worse because you have used up all your "A" material. Particularly this time as it pretty much has to be all new material. It will be easy enough to come up with a bunch of "name the author", "name the film" questions and a few pictorial identifications (the quiz is a powerpoint presentation), but you do need to have something a bit extras. A few questions that are a bit distinctive - things that are entertaining over and above the basic fun of answering questions.

I'm looking for ideas here.

In the meantime, if you want a question from this year's NZ natcon...

Are You Watching Closely? One was Batman, one was Wolverene but when they came together for a film, their characters’ initials run together to start the word abracadabra. What movie of prestidigitation does this describe?
