Willem Dafoe lends voice to documentary 'Mountain'Los Angeles, May 29 (AZINS) Actor Willem Dafoe is lending his voice as a narrator to documentary "Mountain", which "explores the troubled and triumphant history of our timeless fascination with mountains".

The film from director Jennifer Peedom and British writer Robert Macfarlane (author of "Mountains of the Mind") has been in the Cannes film market and will be released in cinemas in Australia on September 21 by Madman Entertainment.

"I was looking for a very particular voice to carry this film," said Peedom, reports hollywoodreporter.com.

"Given the nature of the collaboration, the voice itself needed to be an instrument in order to carry the poetry of Robert Macfarlane's words and to hold up alongside the powerful score curated by Richard Tognetti. But it also needed to feel authentic. Willem Dafoe brought both those things to the film."

The Australian Chamber Orchestra (ACO) will next month present the world premiere in a special event dubbed "Mountain Live", a cinematic and musical collaboration that will feature the ACO performing live onstage alongside a screening of the film.

The June 12 event will take place at the Sydney Opera House as part of the Sydney Film Festival. The ACO will then tour "Mountain Live" throughout Australia in August.

ACO artistic director Tognetti worked with Peedom to curate a soundscape that "mirrors the serenity, magnitude and terror of the landscapes featured in the film".
