Pitt is in town to push his Quentin Tarantino-helmed Inglourious Basterds and Jolie is likely to get time off from filming Salt to join him May 20. It will be the third time in a row the pair have jetted in, with Jolie attending last year while pregnant with twins.
Other celebrities to watch out for are Academy Award-winner Penélope Cruz, whose Broken Embraces, directed by Pedro Almodovar, is in competition, and actress Robin Wright Penn, who is a member of the jury panel.
The festival opened with Disney/Pixar’s 3D movie UP getting the big push with a glamorous party and photo-driven stunts on beach of the Mediterranean.
The movie world will be watching to see what effect the downturn in the world’s economy has had on the normally splashy festival. While some regular showbiz parties have been cancelled, the fashion brands such as Dolce & Gabbana, Chopard (as co-sponsors) and D Squared will be hosting events on or just off the Croisette.
In the second half of the ten day fest, the annual amfAR bash promises an appearance by former President Bill Clinton among regulars like Sharon Stone, Donatella Versace and movie executive Harvey Weinstein.
