The 15th Academy Awards was held in the Cocoanut Grove at The Ambassador Hotel in Los Angeles on March 4, 1943, honoring the films of 1942. The ceremony is most famous for the speech by Greer Garson; accepting the award for Best Actress, Garson spoke for nearly 6 minutes, considered to be the longest Oscars acceptance speech. Irving Berlin presented the Academy Award for Best Original Song, which he ended up winning himself for "White Christmas". There was a four-way tie for Best Documentary Feature, a unique occurrence. A portion of the ceremony was broadcast by CBS Radio.
