As it turned out, Cavendish showed little interest (too busy correcting his students' Abitur exams), but BimoDad seemed quite keen on seeing the movie. So I'm going this evening, accompanied by my Dad! :-)

(Which, btw. is a great way to make up for the fact that I had failed to recommend The Hunger Games to my father early enough so he could see Catching Fire while it was still playing in cinemas. I don't think there's any doubt from whom I have inherited the more fannish traits of my personality *g*)
