Robert Wise and Marc Breaux, on their initial "The Sound of Music" Salzburg location survey of the city's streets and squares, walking, discussing, planning the cutting of shots for each tracking dance sequence involving Maria and the Von Trapp children. Marc, busy with creating the motivation for the dance sequences were followed on the sidewalk by Robert Wise, while Marc planned each choreographed sequence out in the city street traffic lanes. The congested city traffic didn't stop Marc from sailing out into the traffic patterns planning each dance routine. After the film's principle photography in Salzburg had finished, the weather was overcast, the country side shrouded in fog and mist, and heavy daily rain, prevented the opening hill top shot-set-up. The company remained in their hotels waiting for the final sequence filming. Fox management gave the company departure travel orders. The very last day, as Robert Wise tells, the sky opened with a bright glorious sunny morning. The entire company raced to the hill top, with the helicopter loaded with camera and crew, setting up the film's opening sequence of aerial shots, finally coming upon Julie Andrews spinning around on a hill top before breaking into the title song. To get the timing right, Breaux was hidden in nearby bushes. He watched the helicopter coming over the mountains and at the right moment he had a bullhorn, yelled to Julie Andrews, "OK, Julie! Turn!".
