Mobile phones are to be temporarily confiscated duringcertain screenings at this year's Edinburgh Film Festival as part of acrackdown on piracy.

Festival-goers and industry executives attendingscreenings of films such as BVI's Kinky Boots - which world premieres atEdinburgh - will be asked to hand over their phones for the duration of thefilm.

The security move is being facilitated by the festivalbut paid for by distributors.

The concerns have been raised because of next-generationmobile phone cameras, which can take lengthy film clips.

While they could not be used to pirate an entire film,the phones would allow parts of the latest blockbusters to be shown on-linemonths before they were due out in cinemas on general release, as well as usingmovie images for unauthorised purposes.
