The stars of The Paperboy were up early in France to promote their project at the Cannes Film Festival today. Nicole Kidman, Zac Efron, and Matthew McConaughey's morning photocall comes after an appearance on the French show Le Grand Journal just yesterday. Zac opened up about filming mostly in his underwear, saying, "I don't think I was supposed to feel comfortable. It's like life. This character is supposed to be learning the ways of the world, and that can be very uncomfortable. But it's also exciting." The trio will be back in the spotlight later today, when they premiere their movie at the Grand Palais.
