While some level of individual fame on the part of movie actors was almost certainly inevitable, it was greatly encouraged by the Hollywood studios, who promoted individual movie stars. But at first, the studios were reluctant to do this because they assumed (correctly) that the stars would eventually demand more money for doing movies once they became stars. What if that attitude had prevailed, and particular actors (and maybe later musicians) became relatively well-known but not "stars" per se? What would that even look like? Is it imaginable?
