For movies, music and books crowdfunding model can be used. You have some idea about good movie? People like it and want to watch, movie theaters want to make profit from showing it. Anyone will know that if requested amount won't be collected, there won't be this movie at all. So people who are interested in this film will gladly make a voluntary contribution to the film maker. Of course this model fill work if no state-enforced (=imposed by corporations) copyright exist.
