I have movie trailers (Star wars and Casino royale)...?

I have movie trailers used in cinemas. (Star Wars Episode 3, Orange mobile phone advert 'Darth Vader film pitch', and Casino Royale) But as they are designed for industrial cinema use, they are actually on 35mm films, so you can't watch them unless you have a 35mm film projector at home. Do you think I can sell them on the internet one day?
