Boats make a movie more fascinating. They can intensify action and tension in the film, usually when you add changing weather conditions or conflict. They aren’t recognized in the ending credits, but sometimes they hold an important role on the big screen.
Titanic (1997) is a testimony to this. It has become a well-established part of pop culture. It was the first film to reach the billion-dollar mark in sales, and remained the highest-grossing film of all time until Avatar (2009) surpassed it in 2010.
