The 68th Cannes film festival is to kick off at midnight Beijing time.
This year, 19 films are vying for the Palme d'Or.
Mainland director Jia Zhangke's Mountains May Depart and Taiwan director Hou Hsiao-Hsien's The Assassin are among the films in competition for the award.
Jia's movie is a three-part tale spanning several decades that begins with separated lovers in China and ends up in a futuristic Australia.
The director won Cannes' best screenplay award in 2013 for his A Touch Of Sin.
Hou Hsiao-Hsien is a leader of Taiwan's New Wave cinema movement. His movies have been nominated six times for the Palme d'Or, but he has never won.
However in 1993, he picked up the Cannes Jury Prize for In The Hands Of A Puppet Master.
American actor Jake Gyllenhaal, actress Sienna Miller, French star Sophie Marceau, Mexican filmmaker Guillermo del Toro, and Cannes jury presidents Joel and Ethan Coen are among the 9 juries to decide which film will win the big award.
