Reflecting her early political interests as a civil rights worker during the 1960s, many of her social views are expressed in the novel. In The Color Purple, as in her other writings, Walker focuses on the theme of double repression of black women in the American experience. Walker contends that black women suffer from discrimination by the white community, and from a second repression from black males, who impose the double standard of white society on women. As the civil rights movement helped shape Ms. Walker's thinking regarding racial issues at home, it also shaped her interest in Africa. During the 1960s, a strong interest in ethnic and racial identity stimulated many African Americans to look for their roots in Africa. The primary theme of The Color Purple, though, reflects Walker's desire to project a positive outcome in life, even under the harshest conditions. Her central character triumphs over adversity and forgives those who oppressed her. This central theme of the triumph of good over evil is no doubt the source of the book' s great success.
Since the film's premiere 25 years ago, Walker has been asked over and over again, "Did you like the movie?" Although her response sometimes varies, she most frequently answers, "Remember, the movie is not the book" ("The Color Purple: The Book and the Movie"). Walker is right, movies and books are two completely different mediums. That is why Director Steven Spielberg decided to differ slightly from the highly acclaimed novel. Yet, at the same time, he wanted to stay true to Walker's powerful message about overcoming adversity. In the screen translation of The Color Purple, Spielberg creates not only a faithful, but also a successful adaptation, by capturing the novel's central themes, characters, setting, plot and symbols. Another important theme in Walker's novel is the cyclical nature of sexism. Both the novel and the movie show the patriarchal dominance and abuse that black women endure.
