I worked on HP as a stand in for Voldemort. They shaved my hair, put me in the prosthetics and wispy costume (which was a pain in the ass as I kept tripping over it). They didn't cut my nose off, though. In fact, because I'll otherwise have nothing to do with HP (it was only the money that made me do it) I had no idea that my Voldemort had no nose. How did he smell...?
I stood in for that guy with the funny pronunciation of his first name during the bit where Gary Oldman is tortured by a magic wand. Something about "you'll get it for me"? GO stood next to me inbreaks in filming and like all hollywood stars that have stood next to me during breaks in filming totally ignored me. I've been ignored by all the greats, ya know!
So - HP paid for my car, satnav and insurance. So I have no complaints. I still refuse to read/watch any of it, though. (The ministry of magic set was impressive, though. Looked like a train station.)
