In the 1997 film, Stuart played the older incarnation of Kate Winslett's Rose Calvert - the character who turned the movie from a tragedy in which 1,490 people died into a bittersweet tale where a single locket showed love could endure.

She celebrated her 100th birthday July 4 at a lavish Hollywood party attended by, among others, Titanic director James Cameron.
