Natalie Portman's experiences with marijuana helped her appreciate the warrior princess she portrayed in Your Highness. She costarred in the movie with James Franco. "I love stoner comedies. I smoked weed in college, but I haven't smoked in years," she told Entertainment Weekly. "I'm too old. I wish I was that cool, but I'm like an old lady now. I'm in bed by 10 p.m. I can't do that anymore."
