Evoking screen sirens of the sixties, the 27-year-old posed for photographs alongside Justin Timberlake, Garrett Hedlund and Oscar Isaac, before admitting that her vocal talents in the movie left a lot to be desired.

Despite the fact that the picture, directed by Joel and Ethan Coen, has emerged as the front runner in the list of competition movies at the festival, it seems that one of the key characters wasn't allowed into France.

The six different tabby cats who played Ulysses, a pivotal part in the film, weren't at the premiere as none of them were allowed to fly.
