While there is no official "Director's Cut" of the film, you can find these scenes in various formats:

Test audiences absolutely hated this version. It broke the intimate, dreamlike magic of Rose’s final farewell to Jack. Cameron wisely chose the theatrical version, allowing Rose her private moment of closure. Summary: Did Cameron Make the Right Cuts?

A deleted scene features Thomas Andrews (Victor Garber) and Captain Smith (Bernard Hill) discussing the ship's speed and safety. This scene adds context to the tragic events that unfold.

In the theatrical version, Old Rose walks to the stern of the ship alone at night and drops the Heart of the Ocean into the sea. In the alternate version, Lizzy Calvert and Brock Lovett spot her leaning over the railing. Fearing she is suicidal, they rush to stop her. Rose reveals she has had the diamond all along.

The theatrical cut focuses almost entirely on Jack and Rose, leaving the fates of many memorable supporting characters unresolved.
