"And that if you become a star, people are going to go to see you. If you remain an actor, they're going to go and see the story you're in"

Morgan Freeman is clarifying the distinction between being a popular star (a celebrity) and also simply being a star. He suggests that if somebody becomes a star, individuals will go to see them specifically. However, if someone stays a star, individuals will certainly go to see the tale that they belong of rather than just the specific star. Basically, Freeman is emphasizing the value of the tale and also the function of the star within it.
