French star Marion Cotillard showed off her je ne sais quoi at the European premiere of “Public Enemies” in London. The Parisian looked stunning as she walked the red carpet in a red satin strapless, origami front Vivienne Westwood dress with cozy pockets paired with a black Stella McCartney Fall 2009 embossed faux leather clutch. Cotillard’s coif was elegantly slicked back to show off her elegant neck line and simplistic ensemble.

The Oscar-winning actress, 33, is promoting her new movie “Public Enemies” with co-star, Johnny Depp. The waiting crowds went wild for Depp as he walked the red carpet in a dashing pinstripe suit. It’s hard to believe that Johnny Depp is 46-years-old because like a fine wine, he gets better with age.

The actor stars as John Dillinger, the charismatic bank robber whose lightning raids made him the No 1 target of J Edgar Hoover’s fledgling FBI and its top agent Melvin Purvis, who is played by Christian Bale. Dillinger’s charm endeared him to girlfriend Billie Frechette (Marion Cotillard) and captivated an American nation suffering financial hardship. Depp said of the role: ‘I had a sort of fascination, not so much that he was a criminal… that this guy took up arms against the establishment and he did it with a smile. There was a sort of twinkle in his eye which I find interesting.’

Asked if Depp was as charismatic off-screen as on, Cotillard said: ‘He’s a very nice person, a very, very nice person.’
