Which is strange. If the United States were to truly transform into a totalitarian state, or suffer an environmental catastrophe, it's safe to say society’s deepest divisions wouldn't magically disappear overnight. These dystopian adaptations ask their young audiences to imagine that race and gender issues have been partially overcome in the future, while general human suffering has somehow increased. The results feel false, and undercut the films’ attempts to comment on the present day.
This is not to say that these movies don’t occasionally touch upon identity—both Divergent and The Hunger Games clearly have something to say about gender equity, and The Maze Runner gives boys of color some prominent roles. But none imagines a future in which racism and sexism are significant problems facing their protagonists.
For instance, in The Hunger Games films, there is diversity in the cast. District 11, the site of a brutal execution in the second film, is filled almost entirely with black inhabitants. But at the same time, the film implies that white characters like Katniss and Gale now make up the majority of the poorest district (12).
None of the primary characters seems affected by race or are racist. Instead, the film continues the old sci-fi tradition of imagining the subjugation of white people, essentially saying, "Things could get so bad that people who look like Liam Hemsworth are now at the bottom, too!"
Whenever Hollywood does get an opportunity to talk about race in one of these movies, it minimizes the subject. Characters of color like Beetee, Cinna (Lenny Kravitz), who mentored Katniss, or Christina, Tris’s best friend in Divergent (played by Kravitz’s daughter Zoe), certainly play major roles in these stories, but their race is never at issue. You might say that this is an example of admirably "colorblind" filmmaking—were it not for the fact that the audience’s perspective is always that of a white protagonist.
To an extent, the diversity of characters depends on the source material, but producers typically have some leeway in casting decisions. Suzanne Collins, in her original novel, does not explicitly describe Katniss as Anglo-Saxon (she has “olive skin”), so it’s actually the filmmakers who make the decision to default to white. In fact, Collins intentionally leaves many lead characters in the novels racially ambiguous, creating a more integrated and nuanced world.
When the first Hunger Games film decided to cast black actors in the roles of Cinna and Rue, many fans of Collins’s book (who had imagined the characters differently despite the novel’s clear description of their “dark brown” skin color) were upset, but they still went to see the film in droves. In the sequel, Jeffrey Wright was cast as Beetee, who is in fact described as having “ashen” skin by Collins.
