Palais des Festivals in Cannes, France An epic lesbian love story with graphic sex, a Coen brothers musical comedy and a blood-stained critique of Chinese society rocked the 66th Cannes Film Festival but critics said no hands-down favourite had emerged ahead of Sunday's prizes. After 20 films in competition in what reviewers said was a fairly strong year at the world's top cinema showcase, at least a quarter of the pictures looked like possible winners of the Palme d'Or top award.
A jury led by Steven Spielberg and packed with fellow Oscar winners Nicole Kidman, Ang Lee and Christoph Waltz among other luminaries was to deliberate in seclusion at a villa in the hills above Cannes.

At three hours in length, the picture follows the arc of lead character Adele's (Adele Exarchopolous) tender passion for a beautiful blue-haired art student played by rising star Lea Seydoux, while also exploring themes such as class in France and women's careers.
"Sure to raise eyebrows with its show-stopping scenes of non-simulated female copulation, the film is actually much more than that: it's a passionate, poignantly handled love story," a Hollywood Reporter critic said.
"Remarkably, though, the explicit scenes never really feel pornographic, especially since the film isn't about titillation or arousal."
It topped critics polls in trade journals Screen International and Film Francais as well as London bookmakers' rankings.
But reviewers wondered whether the jury would shy away from rewarding its lengthy depictions of on-screen lovemaking -- among the most explicit in Cannes competition history.
Joel and Ethan Coen's Inside Llewyn Davis starring Carey Mulligan, Justin Timberlake and newcomer Oscar Isaac in the title role delighted audiences with a mix of soulful 1960s folk singing and absurdist humour.

China's Jia Zhangke offered a shocking look at rampant corruption and exploitation of average citizens in his country that builds into a violent rage with "A Taste of Sin".
US website Salon called it "an art-house film with the body count of a Die Hard sequel while London's Daily Telegraph said it depicted China as "cold and almost unnavigably vast; a place where sin may be the only thing we have to keep us warm."
Iranian Oscar winner Asghar Farhadi made a strong showing early in the festival with The Past an intricately structured drama about a patchwork family set in France.
Other likely contenders included US director Alexander Payne's recession-era road movie Nebraska and lush Roman society portrait The Great Beauty by Paolo Sorrentino.

A few films left audiences entirely cold, with loud booing and mass walkouts for the biggest disappointments.
