Almost all the Titanic scenes are edited from S.O.S. Titanic (TV) (1979).
No main character mentions the 'Titanic' by name throughout the movie. The only person to say the ships name is the paper boy, after the sinking. The word 'Titanic' can of course be read on the newspaper billboards, the life-ring just prior to the collision and on the ship itself as it flounders.
