What are some similarities in theme between the book THE HELP by Kathryn Stockett and the film MISSISSIPPI BURNING?

Both works deal with Southern life at the height of
segregation practices.  They both reveal the different worlds that existed between
Southern Whites and Blacks.  Both works also explore how race was used as a dividing
line between both groups that often kept both at unhealthy distances, increasing
antagonisms and misunderstandings between them.  Another theme between both is that one
sees White Americans seeking to try to bring the narrative of African- Americans into
focus.  Eugenia strives to bring the stories of "the help"out in full force from the
elderly generation, embodied by Abileen, to the perceptions of younger anger, as
embodied by Minny.  In the same light, the FBI Agents Anderson and Ward try to solve the
muder of the three Civil Rights Workers.  In doing so, they are trying to bring to light
the caustic reality of racism on Southern African- Americans.  Both works seek to bring
to light the predicament of those who are silenced by a prevailing social and political
order.
