The release of Irish actor Colin Farrell's new movie in the US may be postponed following the sniper attacks that have taken place in the Washington area.

Farrell plays a man who is imprisoned in a phone booth by a mystery sniper in the film, 'Phone Booth'.

'Phone Booth' had been due for release in America on 15 November, but a spokesperson for 20th Century Fox has said they are now considering delaying the release.

The sniper has so far killed eight people and wounded two.
