The film's running time was originally 120 minutes. Producer Mervyn LeRoy realized that at least 20 minutes needed to be deleted to get it down to a manageable running time. Three sneak previews aided in his decision of what to cut. The original film in its entirety was only seen once by an audience in either San Bernardino or Santa Barbara, and it was the only time the famed Jitterbug number was seen by the public. After this preview LeRoy cut the aforementioned Jitterbug number and the Scarecrow's extended dance sequence to "If I Only Had a Brain." A second preview was held in Pomona, where the film ran 112 minutes. After the preview LeRoy cut Dorothy's "Over The Rainbow" reprise, a scene in which the Tin Man turned into a human beehive, and the Emerald City reprise of "Ding Dong, The Witch is Dead," as well as a few smaller scenes and dialog, notably two Kansas scenes in which the Hickory character was building a machine to ward off tornadoes, as well as dozens of threatening lines by the Wicked Witch of the West. By the third preview, held in San Luis Obispo, the film finally was down to its 101-minute running time, where it has remained ever since.
