In titanic film does the old lady throws necklace in so it will be found or lost forever?

You're likely thinking of the scene in Titanic where Rose throws the "Heart of the Ocean" necklace into the sea.

It's not clear whether she intended for it to be found or lost forever. The film leaves this ambiguous.

Here's why:

* Rose's emotional state: She's clearly in distress after the sinking, and the necklace represents a life she's leaving behind. She might have tossed it in a moment of anger or despair, not thinking about its future.

* The depth: The ocean is vast, and the necklace likely landed at significant depth. Recovery would be incredibly difficult, if not impossible.

* The film's symbolism: The necklace represents the loss of the old life Rose is leaving behind, and its fate in the ocean could symbolize the impossibility of retrieving the past.

Ultimately, the director chooses to leave the necklace's fate open to interpretation. It's up to each viewer to decide whether they believe Rose wanted it to be found or lost forever.
