San Francisco Frontiers - Cannes honours Ford at Indiana Jones premiere

The star, who has vowed this will be the last time he dons the famous fedora, showed a rare bit of emotion as the Cannes Film Festival presented him with an honorary Palme d'Or on stage ahead of the screening.

"I'm very moved by this," he said following a collage of clips from his many hit movies. "I just saw my life flash before my eyes."

The fifth outing for the world's favourite adventuring archaeologist, due for general release in late June, sees the 80-year-old de-aged by several decades using special effects that ate up a large chunk of its $294 million budget.

The extended flashback, that takes up the first chunk of the film, sees a younger Indy in World War II in an action scene on a Nazi train.

The film then flashes forward to 1969 with the professor on the brink of retirement and needing a fresh adventure.

He finds himself racing across Tangiers, Sicily and New York in pursuit of a former Nazi scientist, played with relish by Mads Mikkelsen, and a treasure that would allow him to travel through time.

British actress Phoebe Waller-Bridge plays Jones's goddaughter, and joined the cast on the red carpet in Cannes.

It is the first of the five films -- which began back in 1981 with "Raiders of the Lost Ark" -- not to be directed by Steven Spielberg.

Spielberg passed the reins to James Mangold, known for "Logan" and the Johnny Cash biopic "Walk The Line".

He told AFP that Ford was still "pretty fit" for his age, but it was important to have a story that was "honest, and addressed time, aging and regret".

The first reviews, however, were middling, with the Irish Times saying "nobody with a brain in their heads will compare (it) favourably to the first three films".

But Britain's Radio Times gave it four stars, saying it was "a little safe, but it's an enjoyable, old-school action-adventure".

- Long docs -

Oscar-winning "Twelve Years a Slave" director Steve McQueen was on the red carpet, having arrived in Cannes for his four-hour documentary about wartime Amsterdam, "Occupied City".

Playing out-of-competition on Wednesday, McQueen's doc wowed some critics while boring others.

Premiering at the festival just after Indiana Jones was "Black Flies", a tense drama about New York paramedics starring Sean Penn, with an unlikely supporting role for ex-boxer Mike Tyson as his station chief.

There was another lengthy documentary showing on Thursday from a master of the genre, Wang Bing, who offers rarely seen insights into daily life in China.

His 210-minute film, "Youth (Spring)", came from five years of footage of migrant textile workers around Shanghai and is a rare documentary in the main competition for the Palme d'Or at Cannes.

There are 21 films competing for the top prize at Cannes -- the Palme d'Or -- including several previous winners such as Japan's Hirokazu Kore-eda, Germany's Wim Wenders and two-time British winner Ken Loach.
