Can anyone think of some questions about the show 'Being Human' I can ask? (For work experience)?

I am 15 years old and am doing my work experience next week with the BBC, working on the set of a show called Being Human. In order to express my interest in the show I tink I need to come up with some questions can ask while working there but my mind is blank, so I was wondering if anyone can think of any questions I could ask to any members of the cast or crew? It can be literally anything! Thank you so much in advance for any replies!!!
