The 45th Academy Awards were presented Tuesday, March 27, 1973, at the Dorothy Chandler Pavilion in Los Angeles, California, honoring the best films of 1972. The ceremonies were presided over by Carol Burnett, Michael Caine, Charlton Heston, and Rock Hudson. The ceremony was marked by Marlon Brando's boycott of the Oscars and his sending of Sacheen Littlefeather to explain why he couldn't show up to collect his Best Actor award for The Godfather, and by Charlie Chaplin's only competitive Oscar win for Best Original Dramatic Score for his 20-year-old film Limelight, which was eligible because it did not screen in Los Angeles until 1972. Chaplin had received honorary Academy Awards in 1929 and 1972. Cabaret, Bob Fosse's adaptation of the Broadway stage musical, set a record for the most Oscars won without winning Best Picture. Best Picture winner The Godfather received only three Academy Awards. This year was the first time that two African American women received nominations for Best Actress. This was also the first year when all the Oscar winners were brought out on stage at the end of the ceremony.[4] The show drew a television audience of 85 million viewers.
