By a Waterfall

Choreographic arrangement in "Footlight Parade" by Busby Berkeley that features his trademark human waterfall. It features a crowd of chorus girls diving and swimming into the water in various geometric and floral patterns.

Berkeley realized that screen choreography involved the placement and movement of the camera as well as the dancers. Instead of filming numbers from fixed angles, he set his cameras into motion on custom built booms and monorails and if necessary, cutting through the studio roof to get the right shot.
