Trivia: In the boating scene, Kym Karath (Gretl) nearly drowned when she fell in the water. The scene originally called for Julie Andrews (Maria) to pull her out of the water as Kym couldn't swim, but Andrews fell out of the wrong side of the boat. In fact, the crew had to stop filming to rescue Kym. In the movie Heather Menzies (Louisa) pulls her out - Kym threw up on her after swallowing so much water.
