The latest epic from Titanic director James Cameron had its UK premiere last week, amid claims that it will herald a new era in 3D film. According to Cameron, 3D technology can be expected to become a regular feature in living rooms worldwide, helping to combat piracy in the process.

Speaking to Channel 4 News ahead of the London unveiling of £300-million science fiction extravaganza Avatar, the veteran director explained that the potential of 3D was "absolutely" one of the drivers for getting the movie made. Not only will it tackle piracy, he claimed, but also "the tendency for people to download films onto smaller and smaller devices", instead promoting the attractiveness of "big-screen immersive cinema".

"I think 3D is here to stay, it is going to become more and more ubiquitous because it’s going to be used in more and more films," he remarked. "It is going to move into the home, we will be watching our sports in 3D."

Cameron's comments follow Optoma's American unveiling of its first 3D-ready HD home cinema projector, the HD66 - already hailed by analysts as "one of the cheapest ways" to get a high-definition picture at home.
