Titanic launch day ticket from Belfast to go under the hammer in New York

A friend was an extra,for six months, on the Titanic film near Ensenada, Mexico. He had an interesting story. He was cast as an Irish emigrant for most of the six months he was there. One day they needed more "upper class" extas and changed his assignment. During the shoot the "lower class" extras and the "upper class" extras wouldn't mingle during meals; the "upper class" extras actually thinking they were "better" than their fellow extras. When my friend was changed to First Class he was asked it it was his first day on the film. He advised them that he had been with them everyday for months. Quite a social experiment.
