A $7 million, 25,000-square-foot new replica of "Titanic -- Ship of Dreams" opens in Orlando Saturday and will combine 200 artifacts and memorabilia, including a costume worn by Leonardo DiCaprio in the movie blockbuster. Gloria Stuart, who was nominated for an Oscar for her role in the film, is expected to be on hand for a black-tie gala Friday, along with Muffet Brown, the 36-year-old great-granddaughter of Molly Brown, the legendary Titanic survivor dubbed "unsinkable." "As long as it's tasteful and you don't have people going around in lifejackets making fun of the event, I think it will be nice," Brown said Wednesday from her home in Los Gatos, Calif.
