Loveless is a Russian drama film directed by Andrey Zvyagintsev, which has been selected to compete for the Palme d'Or in the main competition section at Cannes.

The movie has won rave reviews, with The Guardian lauding the film stating: 'Andrei Zvyagintsev’s Loveless is a stark, mysterious and terrifying story of spiritual catastrophe...

'A drama with the ostensible form of a procedural crime thriller. It has a hypnotic intensity and unbearable ambiguity which is maintained until the very end.'

Sizzling: Adriana pulled her very best pout for the cameras 

Woo! Petra dropped the smouldering pout as she larked around
