The professor, who graduated from Yale University with a history degree in 2001 and earned his doctorate in English from Harvard University nine years later, also notes that “minstrel history” associated with blackface and racial commentary is not limited to “Mary Poppins.” He says it is “a mainstay” of Disney musicals, including the jiving blackbird in the 1941 film, “Dumbo,” and a 1933 Mickey Mouse short, “Mickey’s Mellerdrammer,” which parodies “Uncle Tom’s Cabin.” Pollack-Pelzner cautions, however, that the new film is “bound up in a blackface performance tradition” that persists throughout the “Mary Poppins” genre. He calls the new film “an enjoyably derivative film that seeks to inspire our nostalgia for the innocent fantasies of childhood, as well as the jolly holidays that the first ‘Mary Poppins’ film conjured for many adult viewers.” Pollack-Pelzner’s article comes as “Mary Poppins Returns” picked up four Academy Award nominations last week.
