Although director Sook-Yin Lee is a character in the original graphic novel, for the film adaptation she chose to rename her character Sonny to give herself some creative distance from the material.
In contrast to the original graphic novel, which used artistic techniques to obscure the faces of the sex workers due to Brown's concern for the women's privacy rights but faced some criticism for seemingly dehumanizing them, Lee's film adaptation tells the story through a "female gaze," which more strongly centres the women's own perspectives.
