 In 2007 , Tarantino discussed an idea for a type of Spaghetti Western set in the United States ' pre @-@ Civil War Deep South . He called this type of film " a southern " , stating that he wanted " to do movies that deal with America 's horrible past with slavery and stuff but do them like spaghetti westerns , not like big issue movies . I want to do them like they 're genre films , but they deal with everything that America has never dealt with because it 's ashamed of it , and other countries don 't really deal with because they don 't feel they have the right to . " Tarantino later explained the genesis of the idea : " I was writing a book about Sergio Corbucci when I came up with a way to tell the story . ... I was writing about how his movies have this evil Wild West , a horrible Wild West . It was surreal , it dealt a lot with fascism . So I 'm writing this whole piece on this , and I 'm thinking : ' I don 't really know if Sergio was thinking [ this ] while he was doing this . But I know I 'm thinking it now . And I can do it ! ' "
