Earlier in the day, Pitt joined his on screen leading lady, Diane Kruger (in a vintage strapless dress and fine jewelry by Chanel), at a photocall for the Quentin Tarantino flick. Asked about his Riviera style by the Today show's Anne Curry, Pitt revealed that he had been "personally dressed," by designer Tom Ford for the occasion.

Abbie Cornish chose a lilac gown by designer-and fellow Australian-Toni Maticevski for the premiere of Bright Star at the Palais Des Festivals.
