It would have been messy if the movie didn't get this approval

Both the actual Macy's and Gimbel's department stores were approached by the producers for permission to have them depicted in the film. Both stores wanted to see the finished film first before they gave approval. If either store had refused, the film would have had to been extensively edited and reshot to eliminate the references. Fortunately at the test viewing, both businesses were pleased with the film and gave their permission.
