Film director 'sees future in 3D'

Film director James Cameron has said Hollywood should release more digital 3D movies as a way of luring people back into cinemas and reducing piracy.
He told a US media conference he was considering a 3D reissue of Titanic, according to the Hollywood Reporter.
He described the format as "a powerful experience" which could be used while shooting new releases or to offer a fresh perspective on classic films.
He said he would not make movies "for people to watch on their cellphones".
Cameron added: "I don't want that grand, visionary, transporting movie experience made for the big screen to become a thing of the past."
Special filming techniques
Several forthcoming films are being produced using 3D-compatible methods.
A remake of Journey to the Centre of the Earth will be shot in live action with so-called "stereographic" cameras.
Beowulf, directed by Robert Zemeckis, will use 3D filming techniques, while Walt Disney's computer-animated Meet the Robinsons will be projected in 3D.
George Lucas plans to reissue his original Star Wars movie in the format next year to mark its 30th anniversary, while director Peter Jackson has a similar idea - at some stage - for King Kong.
Cameron told the National Association of Broadcasters' Digital Cinema Summit in Las Vegas the movie industry needed "to fight back harder, come back blazing, not wither away and die" in response to falling ticket sales in cinemas and increases in incidents of piracy.
International film box office revenues dropped by nine per cent in 2005, according to the Motion Picture Association of America.
Only four films made more than $300m (£168m) outside the US, compared with seven in 2004.
