Cameron: 3D can be used on smaller films
Speaking to the Brisbane Times, Cameron said that while he will only be involved as a producer on the Australian drama, he hopes to use it as an opportunity to show how 3D can be used on smaller, more personal films.
"It's really a character driven piece and the 3D should only be part of enhancing the experience. If you take the 3D away from the film and you take the spectacle away from the film, it's still a strong story," he added.
Sanctum follows the real-life story of a father and son trapped in a remote underground cave system.
It will star Van Helsing's Richard Roxburgh and Alice Parkinson of X-Men Origins: Wolverine.
Cameron, whose past projects include Titanic and Terminator, spent the best part of a decade working on the 3D technology needed for Avatar.
The film went on to be the highest-grossing movie ever.
