The producer beating a new path for himself through the wilderness is going to do the thing 'differently,' of course. But after a while, he looks about him. The territory is unfamiliar, the forest ahead forbidding. Just how 'different' dare he be? He looks at his resources, and then at the established successes of the past. He suddenly realizes he must play safe, be sure. The unknown is a gamble; the known isn't-at least comparatively. The safest plan, obviously, is to follow the trailblazers. So he produces an imitation of one of the current successes. Usually it is a mediocre imitation.
