1. 20 producers on one film would lead to nothing but a big ol' heaping mess, cuz that's 20 cooks in one kitchen. When ppl put their money in something, they feel they should have some element of control.

2. Even if the 20 managed to make the film, they'd have to go to Hollywood to get it distributed - if they wanted it reach a large # of ppl.

3. If they manage to distribute it on their own, they have to compete w/the big studios for screen space. There are only so many screens in the country - in the major theaters, that is. Of course they could make their movie and take it around to the smaller, independent movie houses, but those are drying up daily. Those that are around aren't tied into local marketing channels well enough to reach mass audiences - or they don't have the physical capacity to deal w/mass audiences.

4. They'd have a hell of a time getting any press coverage for the film b/c the press is in bed w/the studios.

It could be done....sure.
