Cameron edits 900 hours for new flick

Titanic writer-director James Cameron had to edit 900 hours of film into just one hour for his latest project, the 3-D documentary Ghosts Of The Abyss.

The filmmaker and his crew made several dives to the wreck of the Titanic to gather the material for the state-of-the-art film which takes cinemagoers on an unscripted tour of the shipwreck.
