Leonardo DiCaprio & Carey Mulligan with Amitabh Bachchan cuddle up on the red carpet in Cannes

The Cannes Film Festival got off to a blockbuster, if stormy start, as Baz Luhrmann's "The Great Gatsby" opened on a soggy French Riviera.

Amid heavy rain, dancing flappers flocked down the Cannes red carpet Wednesday night, bringing a touch of the Jazz Age to the Croisette. "Gatsby" stars Leonardo DiCaprio, Carey Mulligan and Tobey Maguire helped give the festival's opening day a strong dose of star power.

At the opening ceremony, DiCaprio, joined by his "Gatsby" co-star, Bollywood actor Amitabh Bachchan, declared the 66th Cannes officially begun.

Over the next 12 days, dozens of the world's most artistically ambitious films will premiere on Cannes' global stage. But Wednesday was a day for blockbusters - both the big-budget "Gatsby" and Hollywood's most accomplished director of spectacle: Steven Spielberg.

Spielberg is serving as jury president at this year's Cannes. His presence here is a rarity (he's had films at Cannes before, including "E.T." and "Sugarland Express," but never had a movie in competition), and he was received like a visiting head of state, a king of cinema.

The "Lincoln" director received a standing ovation at the opening ceremony and was serenaded with a performance of "Miss Celie's Blues" from his 1985 film, "The Color Purple."

 
For the occasion Carey opted for a stunning black jumpsuit which she paired with black heels while Isla wore and equally fetching white frock also with black heels.
