I'd like to see a crossover between Star Trek and Doctor Who and on the big screen too. Seeing the Enterprise fighting a Dalek battle fleet would be a geek delight for the ages.
It might even top seeing the 'Death Star trench' scene from A New Hope in a theater.
I'm afraid I don't know enough about Doctor Who to know what that means. Were the Daleks one of those two societies at nuclear war in the 80s(?)?
