A film edited in iMovie has been a surprise hit at the Cannes Film Festival, earning a standing ovation when it was screened.

Tarnation is an autobiographical home movie, directed and written by Jonathan Caouette. It consists of a mixture of photos, film footage and answer-phone messages, and cost only £124 to make.

Caouette told The Guardian: "Making a movie is not as difficult as it's made out to be. Hopefully this will be a catalyst for people who didn't have a voice before to go out and make a movie."
