What was the first musical movie?
Musical film
Hollywood released more than 100 musical films in 1930, but only 14 in 1931.[4] By late 1930, audiences had been oversaturated with musicals and studios were forced to cut the music from films that were then being released. For example, Life of the Party (1930) was originally produced as an all-color, all-talking musical comedy. Before it was released, however, the songs were cut out. The same thing happened to Fifty Million Frenchmen (1931) and Manhattan Parade (1932) both of which had been filmed entirely in Technicolor. Marlene Dietrich sang songs successfully in her films, and Rodgers and Hart wrote a few well-received films, but even their popularity waned by 1932.[4] The public had quickly come to associate color with musicals and thus the decline in their popularity also resulted in a decline in color productions.
