Wim Wenders' Don't Come Knocking, featuring Edge and Bono on the soundtrack, opens in the US today.

Last year, despite the small matter of being in the middle of a world tour, Bono and Edge took up an invitation from longtime friend Wim Wenders to write the title track for his latest film Don't Come Knocking.

The film, a western starring Sam Shepard, Jessica Lange and Tim Roth, won rave reviews at the Cannes Film Festival and today opens in Los Angeles and New York.

With Edge on guitar and Bono - joined by Andrea Corr - on vocals, the track was produced by Garret Lee in a hotel in Amsterdam when the band were playing the city last summer. It was a close call according to Wim, who said that Bono and Edge had been planning to write a title track for the film but the pressures of the touring schedule nearly made it impossible.

'Our deadline was coming closer and closer and it was a very simple one. When we had to start making release prints, it would be too late. I kept that date open as long as possible and never gave up the hope that things would work out in the last minute. And they did! Literally in that last minute the song came in!'

But it was worth the wait, he says.

'I got goose pimples when we first heard it and saw it with the picture. It has heartbreaking lyrics and the duet with Bono and Andrea Corr is stunning... I can't wait for you to all hear it!'
