there is a company out of washington state ( seatle ) that sells motion picture film in 35mm canisters. you shoot it, and send it back to them for processing. from the same roll you can have it processed for slides or for prints. they used to be called seatle filmworks, now they are photoworks.
a friend swears by them and i have seen the results, they do pretty good work ...
from what i have read + heard they use the "ends" from the film industry.
