The "at sea" scenes were filmed on board QE 2. At the time, the QE 2, in a fit of "Modernism" had the top of the deck railings made out of composition rather than wood. In shots where the railing would be visible, the crew had placed wood design, contact sticky shelf paper over the plastic to give the appearance of a wood railing rather than black plastic. The railings on the QE 2 have since been replaced with real wood!
