CANNES, France, May 14, 2024 (BSS/AFP) - Cannes rolled out the red carpet on Tuesday as Hollywood stars jetted in for the start of the world's premier film festival, which this year unfolds against the background of a director's daring escape from Iran and fresh #MeToo allegations.

The 12-day festival officially kicks off in the evening with an honorary award for Meryl Streep -- one of a host of A-listers flocking to the Cote d'Azur alongside legendary directors George Lucas and Francis Ford Coppola.

Coppola's decades-in-the-making epic "Megalopolis", an Ancient Rome-inspired saga set in a corrupt modern-day city, is the most anticipated of this year's entries for the top prize Palme d'Or.

"Cannes is important to him and he is important to Cannes," said festival head Thierry Fremaux, praising the 85-year-old director of "The Godfather".

Twenty-two films are competing for the affections of a jury led by "Barbie" director Greta Gerwig.

"I'm pinching myself. This is a marvel," she told reporters.

Richard Gere will star in Paul Schrader's "Oh Canada", recent Oscar winner Emma Stone reunites with Yorgos Lanthimos in "Kinds of Kindness", and Demi Moore tries her hand at horror in "The Substance".

Outside the race for the Palme d'Or, George Miller's latest "Mad Max" instalment, "Furiosa", will get its world premiere on Wednesday, while Kevin Costner returns to the Western genre with "Horizon, an American Saga".

But darker, off-screen plotlines have emerged on the eve of the festival's 77th edition.

In a last-minute twist, director Mohammad Rasoulof -- also competing for the Palme d'Or -- announced he had escaped in secret from Iran, just days after being sentenced to eight years in prison on security offences.

Rasoulof, who had been under pressure from Iranian authorities to withdraw his latest film, "The Seed of the Sacred Fig", from Cannes, urged the world film community to support his colleagues, many of who remain in Iran.

"My thoughts go to every single one of them and I fear for their safety and well-being," Rasoulof said, in a statement to AFP.

Cannes director Thierry Fremaux said the festival was working with the French foreign ministry in the hope of ensuring Rasoulof can attend his premiere next week.

Rasoulof's statement said he did not yet know if he can attend.

- 'Festive moment' -

Meanwhile, France's film industry is in the midst of a belated #MeToo reckoning, with a string of accusations against its biggest star, Gerard Depardieu, and rumours that more big names will face accusations.

Gerwig said the #MeToo movement was "evolving all the time".

"It's not a destination we all reach together, it's something we will keep discussing and figuring out how we want our industry and cinema to be," she said.

A major French producer, Alain Sarde, was hit with multiple assault allegations on Monday.

Camille Cottin, star of hit television series "Call My Agent!" and an outspoken feminist, will host the opening ceremony.

She said there were a lot of issues she would like to address in her speech.

"But it's also supposed to be a festive moment... and I've only got four minutes," she told AFP.

Adding to the off-screen drama, a group of festival employees have called for a strike over pay and conditions that could cause disruption.

- Trump, Coppola, Stone -

Among the entries for the Palme d'Or is "The Apprentice" -- a biopic of Trump's formative years from Iranian-born director Ali Abbasi, starring Sebastian Stan, known for playing the Winter Soldier in Marvel films.

Film fans are also excited for new works from body-horror maestro David Cronenberg ("The Shrouds"), Italy's Paolo Sorrentino ("Parthenope"), as well as "Emilia Perez", an unlikely-sounding musical about a Mexican cartel boss having a sex change from French Palme-winner Jacques Audiard.

But the hot ticket is undoubtedly Coppola's "Megalopolis", starring Adam Driver, on Thursday.

There is a growing anticipation over whether the veteran director -- who self-funded the lavish epic -- can match his masterpieces of the 1970s, when he twice won the Palme d'Or for "Apocalypse Now" and "The Conversation".

Playing out of competition is "She's Got No Name", one of China's biggest-ever productions, which features megastar Ziyi Zhang tackling the highly sensitive topic of women's rights.

Legendary Japanese animators Studio Ghibli -- makers of "Spirited Away" and "My Neighbour Totoro" -- will receive an honorary Palme d'Or, the first offered to a group rather than an individual.

The festival will round off on May 25 with a final honorary award for "Star Wars" creator Lucas.
