Still remember the opening scene where Julie Andrews, who played the role of Maria von Trapp, was twirling on the mountaintop? The scene was shot from a helicopter. It was raining and cold throughout the shot and the down draft from the helicopter kept knocking Andrews down. Andrews was knocked down by the downdraft at least five of the ten takes they shot for the scene. You’d never know that she was forced into the grass and mud whilst spinning and lip-syncing.
