Metallica's Lars Ulrich confessed he was surprised by the pace at the Cannes Film Festival, insisting it had been really hard work.
The drummer is at the festival promoting the band's upcoming film Metallica Through The Never. Directed by Nimrod Antal it stars young Chronicle actor Dane DeHann as a member of Metallica's concert tour crew who's sent on a special mission by the band.
Lars said: "Most people have a romantic notion of Cannes. But there is a lot of work that goes on here. And I was a little bit unprepared for basically the whole infrastructure of worldwide cinema and the movie business (that) is here," he said in an interview.
"People have a tendency to think that is just red carpet and movie stars and sipping champagne but people come here to work. People come here to sell their films, people come here to finance their films, people come here to create hype."
Metallica Through The Never marries the concert film format with a dramatic narrative, blending concert footage with a plot that includes CGI effects.
"We wanted to challenge ourselves a little bit and try and do something different and try and bring a little bit more of a film element into it," explained Lars.
"Whether anybody loves the film as much as we do we'll have to wait and see in a few months, but the one thing I can guarantee you, which there is no question about, is that it is a very unique film. Nobody has ever seen a film quite like this."
Metallica Through the Never is due out in cinemas in September.
