Story highlights King, Stone and Riseborough talked for Out magazine

Stone said she sees parallels between King's time playing and now

(CNN) Emma Stone may be playing tennis legend Billie Jean King 40 years after King's most famous match, but the two still have something in common: a problem with gender-based pay disparity in their professions.

King sat down with Stone and Andrea Riseborough, another of the stars of the movie in which Stone is playing King, "Battle of the Sexes," for an Out magazine article . The trio discussed several issues, including pay equity.
