The ultimate prize at this year's Cannes Film Festival is "up for grabs", according to Robert De Niro.
The actor, who heads the jury that will award the coveted Palme d'Or, said he was looking forward to watching the 20 contenders.
He said: "I'm not sure what I'm looking for. We'll sit there and see the movies and figure it out."
Asked how he would compare the films, which include entries from America, Finland and Japan, De Niro said the jury would look at "how important we feel they are in comparison to the other movies ... so it's up for grabs at the moment".
He is joined on the jury by directors and actors including Uma Thurman and Jude Law.
Law said it was "a great honour" to be asked to take part.
He said: "Of course it's a responsibility but I'm in very good company to cope with that responsibility."
