Amid heavy rain, dancing flappers flocked down the Cannes red carpet, bringing a touch of the Jazz Age to the Croisette.
The Great 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 The Great Gatsby co-star, Bollywood actor Amitabh Bachchan, declared the 66th Cannes officially begun.
Amitabh Bachchan, who spoke his opening ceremony lines in Hindi, tweeted later: T 1109 -Acknowledging Cannes in recognising 100 yrs of Indian Cinema, it was absolutely imperative for me to address, in my Mother tongue !
T 1109 -Director of Cannes delighted to hear the 'music of the Hindi language' spoken, it brought in the universality of the occasion !
Big B also tweeted: T 1109 -For a complete alien in the midst of Cannes to be acknowledged, is the proudest moment for me as an Indian ..
T 1109 -The honour and respect meted out by Cannes, incredible. Announcing suddenly for Leonardo di Caprio and myself to open the Festival !
Over the next 12 days, dozens of the world's most artistically ambitious films will premiere on Cannes' global stage. But May 15 was a day for blockbusters, both the big-budget Gatsby and Hollywood's most accomplished director of spectacle: Steven Spielberg.
Steven 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.
He heads the jury that will decide the prestigious Palme d'Or, given to one of the 20 competing films, with entries ranging from the Coen brothers (Llewyn Davis), Alexander Payne (Nebraska) and Steven Soderbergh (Behind the Candelabra).
This year's jury is an intimidating, starry bunch, including Nicole Kidman, Ang Lee, Christoph Waltz and India's very own Vidya Balan.
"Everyone sits in judgment of us," Spielberg said. "So it's our turn."
Luhrmann's 3-D adaption of F Scott Fitzgerald's novel, starring Leonardo DiCaprio, is this year's festival opener, a choice that surprised many since the film opened last week in North America. Cannes typically takes precedence over release schedules, but The Great Gatsby sails to the Croisette after a robust weekend haul of USD 51.1 million.
The Great Gatsby plays out of competition at the festival, but Spielberg should have his hands full with a slate lacking any obvious favorite.
Internationally-respected filmmakers like Roman Polanski (Venus in Fur), Asghar Farhadi (The Past) and Jim Jarmusch (Only Lovers Left Alive) are to premiere their films in competition.
Every year, the Cannes jury president is psychoanalyzed to help predict the Palme d'Or winner. This year is no different, with onlookers guessing that Spielberg will either gravitate toward the kind of warm-hearted films he's best known for, or seek to deliberately contradict that assumption with a more audacious choice.
