Greatest film of all time! Three camera crews. One filming movie of which reality is altered because story strictly follows script. Second films making of movie which involves conditions somewhat removed from rest of the world. Third camera crew is the star, capturing everything else beyond the production. Central Park and the surrounding streets in Manhattan. Mounted police, rugged pickup soccer matches, families enjoying the park, the homeless. Arguably the best attempt at portraying the real world cinematically which is just about impossible to do.
