The 53rd Academy Awards ceremony, organized by the Academy of Motion Picture Arts and Sciences (AMPAS), honored films released in 1980 and took place on March 31, 1981, at the Dorothy Chandler Pavilion in Los Angeles, beginning at 7:00 p.m. PST / 10:00 p.m. EST. The ceremony was scheduled to take place originally on the previous day but was postponed due to the attempted assassination of Ronald Reagan.[2] During the ceremony, AMPAS presented Academy Awards (commonly referred to as Oscars) in 20 categories. The ceremony, televised in the United States by ABC, was produced by Norman Jewison and directed by Marty Pasetta.[3] Comedian and talk show host Johnny Carson hosted the show for the third consecutive time. Two weeks earlier, in a ceremony held at The Beverly Hilton in Beverly Hills, California, on March 15, the Academy Scientific and Technical Awards were presented by hosts Ed Asner and Fay Kanin.[4] Ordinary People won four awards, including Best Picture.[5] Other winners included Tess with three awards, The Empire Strikes Back, Fame, Melvin and Howard, and Raging Bull with two, and Coal Miner's Daughter, The Dollar Bottom, The Fly, From Mao to Mozart: Isaac Stern in China, Karl Hess: Toward Liberty, and Moscow Does Not Believe in Tears with one.
