Nicole Kidman, Zac Efron and Matthew McConaughey Pictures at 2012 Cannes Film Festival Paperboy Photo Call

The stars of The Paperboy were up early in France to promote their project at the Cannes Film Festival yesterday. Nicole Kidman, Zac Efron and Matthew McConaughey's morning photo call came after an appearance on the French show Le Grand Journal on Wednesday. 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."
