Warner Bros. has confirmed that it will not alter its planned release of Baz Luhrmann's The Great Gatsby, starring Leonardo DiCaprio, on May 10, in advance of its screening as the opening film at the Cannes Film Festival five days later. It will be the first time in memory that any film opening the prestigious festival did not have its world premiere there. Reporting on the studio's decision, today's (Thursday) Los Angeles Times theorized that Warner's had reached the conclusion that the advantages of opening the film on May 10 -- ahead of the summer blockbusters that begin crowding the marquees a week later -- outweighed the worldwide publicity that is ordinarily garnered by a film's world premiere at Cannes. At the same time the Festival apparently is betting that the publicity benefit from having DiCaprio and the other stars of the film walking its red carpet will offset the fact that the movie will already have been old news by the time it arrives in Cannes. Festival insiders told the Times that they regard the decision as a one-off exception.
