In Legion, Noah Hawley's new Marvel series on FX, Jeremie Harris plays "memory artist" Ptonomy Wallace. When we first meet Ptonomy, he is a stark contrast to the show's hero David Haller (Dan Stevens); where David is chaotic and uncontrolled—a mess of adolescent powers—Ptonomy is calm beyond his years. "One of the directors for the show, I like the way he described it: ‘Think of Ptonomy as a 70-year-old man. He's seen so much and experienced so much,'" Harris explains. "He does have a very straightforward way of saying things; he says what he means, but in the way that an older person does. Many things that younger folks are worried about, I think that he doesn't let them affect him," he continues.
