After getting a role in this, Suzanne Pleshette was asked if she could swim, because her character did. Pleshette was actually a very good swimmer, but she said that she couldn't so the production would have to give a job to a double to do the scene. When the double showed up, she told Pleshette that she couldn't swim. Pleshette told her not to worry about it, and then proceeded to do the swimming scene, doubling her own double.
