Veteran rockers the Rolling Stones have opened this year's Berlin Film Festival with concert movie Shine a Light, directed by Martin Scorsese.
The British band joined the 65-year-old director on the red carpet to launch a film that Mick Jagger said offered a "really intimate look" at the group.
He said it was "a great honour" to open the 11-day festival, which will see 21 films vie for the Golden Bear prize.
Shine a Light, released in the UK on 11 April, is screening out of competition.
Scorsese is set to follow it with another music documentary on the life of reggae legend Bob Marley, scheduled for release in 2010.
Scorsese, who won the best director Oscar at last year's Academy Awards, used 26 cameras to capture the Rolling Stones on stage at New York's Beacon Theater in 2006.
He said that the nature of their music was "something that has inspired me constantly throughout the years".
"Whenever I saw the show I'd get excited - I wanted to get a camera up there," Scorsese said at a news conference.
"We tried to get as close as possible to the energy of a live concert."
Guitarist Keith Richards said he had been curious to see "what Martin would come up with" and praised the director's unobtrusive approach.
"We didn't even see them, we didn't even know they were there, and that was the important thing to me," he said.

"As far as I'm concerned, we played three nights at the Beacon and Martin happened to capture it on film. It's a beautiful way to do it."
But drummer Charlie Watts admitted he felt self-conscious watching himself on screen.
"I hate it," he told reporters, though he conceded the movie was "beautifully filmed".
Musician Patti Smith - the subject of another music documentary screening at the annual film event - was among the guests at Thursday night's screening.
Also in attendance was actress Diane Kruger, a member of the international jury who will choose the recipient of this year's coveted Golden Bear.
Paul Thomas Anderson's Oscar contender There Will Be Blood is one of 21 films battling to win the award.
Others include Mike Leigh's latest work Happy-Go-Lucky, plus entries from Iranian director Majid Majidi and Japan's Yoji Yamada.
This year's jury is led by Constantin Costa-Gavras, the Greek-born director of Z and Missing.
Organisers announced on Thursday that two of his fellow jurors - French actress Sandrine Bonnaire and Danish director Susanne Bier - had been forced to pull out.
Authorised by Bob Marley's family, Scorsese's as yet untitled film about the reggae legend is set for release on 6 February 2010, which would have been his 65th birthday.
The singing star died of cancer in 1981.
The musician's son Ziggy said he was "thrilled that the Marley family will finally have the opportunity to document our father's legacy".
He said they felt "truly honoured to have Mr Scorsese guide the journey".
