I've always loved movie prop making - especially on the miniature scale. It makes a lot of sense considering my love of miniature gaming, as the techniques and methods of production for both go largely hand-in-hand. If I had known more about the field when I was younger, I would have explored the world of movie prop making as a career as an alternative to writing.
There is an interesting article on io9 that I'm linking here that shows a massive number of behind the scenes photos of the miniature prop making production from Blade Runner. It's well worth a look for some classic sci-fi inspiration.
