Messi, star of Oscar-winning movie "Anatomy of a Fall", which won the top prize at Cannes last year, will return to the festival next week as a red-carpet interviewer to the stars. Using a special 360-degree microphone and camera attached to his back, the Border Collie will chat with stars thanks to an actor behind the scenes. "He's the star... I'm just lending him my voice," said comedian Raphael Mezrahi. IMAGES AND SOUNDBITES
