Viennese Nights is a 1930 American all-talking pre-code musical operetta film directed by Alan Crosland and starring Alexander Gray, Vivienne Segal, Walter Pidgeon, Jean Hersholt, and Louise Fazenda. It was photographed entirely in Technicolor and released by Warner Brothers. Viennese Nights was the first original operetta written especially for the screen by Oscar Hammerstein II and Sigmund Romberg. It was filmed in March and April 1930, before anyone realized the extent of the economic hardships that would arrive with the Great Depression, which had begun in the autumn of the previous year. Although not a box office hit in the United States, the film had long box office runs in Britain and Australia. It is one of the earliest sound films to have a short pre-credit sequence.
