Ament: 'Pearl Jam Film Will Be Tough to Watch'

Ament: 'Pearl Jam Film Will Be Tough to Watch'... Pearl Jam are struggling with scenes from their upcoming Cameron Crowe documentary - because some footage brings back memories they'd rather forget.

The group gave Crowe, a longtime fan, access to rare video clips and backstage interviews and the Almost Famous director is now piecing the footage together for a major retrospective, which will mark the band's 20th anniversary.

But bassist Jeff Ament admits a lot of the film will be difficult to watch.

He explains, "I just saw a rough cut. It was so f**king weird seeing footage of stuff I didn't know anybody was taping at the time. The whole movie is Cameron's love letter to us - but it's equal parts complimentary and really painful.

"It shows our growing pains and some real bad times, including Roskilde... It was just really hard to watch."

Nine Pearl Jam fans were trampled to death during the band's set at the Danish festival in 2000.
