The free previews, held in cities around the world, sold out within hours (crashing mutliple computer servers in the process) of first being offered Tuesday. The screenings will be presented exclusively in RealD 3D.

Cameron's original Titanic earned $1.8 billion upon its release in 1997 and was the top-grossing film of all time for more than a decade until Cameron topped it with Avatar ($2.8 billion).

Cameron and his producing partner Jon Landau have spent years working on the 3D conversion of Titanic, harnessing the innovative technology of StereoD.

The rerelease of Titanic on April 6 coincides with the 100th anniversary of the real-life Titanic setting sail.

Fox has another film opening on Valentine's Day, This Means War.
