We overestimate the passion for movie-star acting that some performers might have. Acting, certainly, is a passion, and a worthy one. But you act to act, you act to perform, you act to find new truths, new depths. You don’t act to become a movie star, and the bigger the star you are, the less acting you’re actually doing. And in the age of superhero movies and endless franchises, your creative expression is limited if you wear a mask and hold a shield and run through explosions.
