THEN AND NOW: The cast of Titanic 20 years after it premiered

20th Century Fox

We'll never let go.

It's been twenty years since one of Hollywood's most doomed love stories hit the screen and audiences fell in love with Celine Dion's "My Heart Will Go On."

To celebrate the momentous anniversary, "Titanic" is returning to theaters. Beginning on December 1, the film will be re-released at AMC theaters. The 20th anniversary re-release celebration will take place for one week.

The nearly 3.5-hour movie is one of the highest-grossing movies of all time, dominated the 1998 award season, and continues to make lists of top movies to see in your lifetime.

Since its premiere in December 1997, the cast of "Titanic" has taken on several more award-winning roles, and Kate Winslet and Leonardo DiCaprio have maintained their friendship.
