Question: What year did the film Peter Allen's former spouse won an Academy Award for come out?

 Primarily known for her Academy Award-winning role as Sally Bowles in the 1972 musical film "Cabaret" directed by Bob Fosse, she is noted for her energetic stage presence and her powerful contralto singing voice. Liza May Minnelli ( ; born March 12, 1946) is an American actress and singer. <SEP> Catherine Elise Blanchett, {'1': ", '2': ", '3': ", '4': "} ( ; born 14 May 1969) is an Australian actress and theatre director.  She has received international acclaim and many accolades, including two Academy Awards, three Golden Globe Awards, three BAFTA Awards, six AACTA Awards, and three Screen Actors Guild Awards. Blanchett came to international attention for her role as Elizabeth I of England in Shekhar Kapur's 1998 film "Elizabeth", for which she won the BAFTA Award for Best Actress, the Golden Globe Award, and earned her first Academy Award for Best Actress nomination.  Her portrayal of Katharine Hepburn in Martin Scorsese's 2004 film "The Aviator" brought her critical acclaim and many accolades, including the Academy Award for Best Actress in a Supporting Role, making her the only actor to win an Oscar for portraying another Oscar-winning actor.  In 2013, she starred as Jasmine Francis in Woody Allen's "Blue Jasmine", for which she won numerous accolades including the Academy Award for Best Actress. <SEP> The Academy Honorary Award – instituted in 1948 for the 21st Academy Awards (previously called the Special Award, which was first presented in early 1929) – is given annually by the Board of Governors of the Academy of Motion Picture Arts and Sciences (AMPAS) to celebrate motion picture achievements that are not covered by existing Academy Awards, although prior winners of competitive Academy Awards are not excluded from receiving the Honorary Award.  Unless otherwise specified, Honorary Award recipients receive the same gold Oscar statuettes received by winners of the competitive Academy Awards.  Unlike the Special Achievement Award instituted in 1972 (and discontinued in 1995), those on whom the Academy confers its Honorary Award do not have to meet "the Academy's eligibility year and deadline requirements."  Like the Special Achievement Award, the Special Award and Honorary Award have been used to reward significant achievements of the year that did not fit in existing categories, subsequently leading the Academy to establish several new categories, and to honor exceptional career achievements, contributions to the motion picture industry, and service to the Academy.  The Academy Honorary Award is often awarded in preference to those with noted achievements in motion pictures who have nevertheless never won an Academy Award.  Thus, many of its recipients are Classic Hollywood stars, such as Lillian Gish, Barbara Stanwyck, Kirk Douglas, and Lauren Bacall. <SEP>  Allen was then Peter Woolnough, when at the age of fifteen he met Chris Bell, part of a singing duo, "The Two Shades".  When the other member of "The Two Shades" departed it was Bell's father who picked the name "Allen Brothers" for Chris and Peter. The Allen Brothers were an Australian cabaret act of Peter Allen and a singer guitarist Chris Bell.  They also sang with "The Barry Sisters", an Australian backing group unrelated to the American Barry Sisters.  The duo broke up at the same time as Allen's marriage to Liza Minnelli and Chris Bell had no further music career.
