Both Hopper and his older sister, Dylan Penn
, have followed in their parents' footsteps by getting into acting. Hopper even has a role in his father's new film, The Last Face
. "I asked if I could PA for it. He said, 'No, you're going to act in it.' I said no, because I'm very shy; I didn't know how to act," he recalls. "He said, 'Well, you'll get paid.' So I was like, 'I'm on board.' After the first day, I fell in love with it."
