Titanic: At Last -- Pat Dowell says the movie "Titanic" FINALLY opens tomorrow across the country. It was originally scheduled for release this summer, but wasn't completed in time. She talks with James Cameron, who scripted and directed the 200-million dollar film... by far, the most expensive ever made. Cameron went to obsessive detail in recreating the ship. He filmed the remains of the actual wreck on the ocean floor and constructed scale sets from the Titanic's original blueprints.
