 Nicole Kidman and Heidi Klum both brought sexy back to Cannes at The Paperboy premiere today.

The film's leading lady, 44, arrived in a rose coloured draped Lanvin dress that cutaway to reveal her toned upper body.

Supermodel Heidi, 38, also opted for a backless gown, but her Marchesa frock was all the more dazzling thanks to metallic detailing.

Kidman's co-star Zac Efron, 24, looked decidedly dapper in a tuxedo as did fellow stars John Cusack and Matthew McConaughey, who was sporting a suit by Spencer Hart.

The film is set in the 1960s, with Efron playing an aspiring writer helping his journalist brother (McConaughey) investigate a possible miscarriage of justice.

In the film, Efron's Jack falls for Kidman's sparky but sultry femme fatale, who is in turn obsessed with a death row inmate (Cusack).

The cast also includes singer Macy Gray as Jack's family maid and surrogate mother, and British actor David Oyelowo as an ambitious big-city journalist.

'I'd been looking as an actor for something raw and something dangerous,' Kidman told reporters at the festival.

'I may be uncomfortable watching the movie. But that's my job - it's my job to give over to something, not to censor it, not to put my own judgments of how I feel as Nicole playing the character. I am there to portray a truth.

'I don't want to be pigeonholed,' she added. 'I'm willing to fail because of that. I just want to try.'
Kidman worked hard to create Charlotte Bless, interviewing women who were in love with convicts and putting together the character's bold look.

'[Director Lee Daniels] said to me, "Look, we've got no money, you're going to have to do your own hair and makeup,'' Kidman said.

She decided to sit down and experimented with fake tan, fake eyelashes and a platinum hairpiece, then photographed the results.

Efron, who spends much of the film in his underpants, said he felt uncomfortable filming  - but that's the way he wanted it.

'I don't think I was supposed to feel comfortable,' the former High School Musical star told reporters in Cannes.

'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.'

The Paperboy has drawn mixed response in Cannes, where it is one of 22 films up for the Palme d'Or, to be awarded Sunday.

But the actors seem to have adored the experience. Efron said working with Kidman had been a dream.

'I've been in love with her for a long time - since Moulin Rouge,' Efron said.

Director Lee's last film, Precious, was a surprise hit that won two Academy Awards in 2010.

His next will be The Butler, the story of a long-serving White House staffer in which McConaughey plays John F. Kennedy and Cusack is Richard Nixon.

Nicole's Dress is Beautiful!

nicole and heidi both look lovely!

Zac Efron is such a young gentleman, i love him!

Nicole wins! she looks divine, sorry Heidi. I'm looking forward to watch this movie

I know Nicole is a tall woman..and i knew that Eac efron wasn't the tallest...but it REALLY breaks my heart to see how short Matthew McConaughey is! - Harrie, London, 25/5/2012 1:31++++++++++++++++++++++++ Nicole is 5ft 10", so with 4" heels 6ft 2" in the photos? That would make McConaughey about 6ft??

Heidi's dress is obviously not backless, you can see the neutral covering and the line where it stops. I admire Nicole for going completely backless- go her!

It's great to see the trolls who love giving Nicole Kidman a hard time in readers comments are no longer getting their way. NK is pure class and it's good to see so many people supporting her.

Nicole, you are all class! Beautiful, beautiful lady.

No treat to see Nicole Kidman's thighs (or the rest of her really !) PS Granny what big hands you've got !!!!
