Production of the ceremony was reported to be far more ambitious and extravagant than previous ceremonies. Art director Bob Keene designed an ambitiously technological stage design for the telecast that used a floor adorned with flashing lights and several 35 foot columns consisting of high-definition video monitors stacked atop each other. The columns were used to display images of previous Oscar appearances as presenters took the stage, nomination packages, and reaction shots of the acting nominees as the winner was being announced. Because of serious technical challenges concerning movement, lighting, and overheating, Keene and his production design team tested the stage at ABC Prospect Studios before installing it at the Shrine Auditorium.
