On the upcoming episode of Oprah’s Next Chapter, Forest Whitaker and David Oyelowo, join the film’s director Lee Daniels to talk to the former talk-show host about what it was like filming in New Orleans, and tackling such a historic tale in Lee Daniels’ The Butler.

The film details the life of Cecil Gaines, played by Forest Whitaker, who was the head White House butler that served eight presidential terms. His wife, [played by Oprah], and son [played by David Oyelowo], also have standout performances among the other actors.

During an interview with Oprah, the actors talk about social justice and how the film serves as a form of protest.

Whitaker is heard in a sneak peak of the show saying, “I mean, there’s different ways of protest.  And I think, more importantly, I should have said it’s a call for us to recognize that we need to stand up at times for issues and social injustice.  This man is doing it by his mere presence.  Sometimes by your simple presence, you can shift an environment.”

The cast members recognize that the people that they portray in the film have paved a way for African-Americans to succeed. Forest Whitaker and Oprah discuss how people should view the occupations of the service-people they play.

In another clip Oprah declares, “None of us would be sitting here today had there not been the maids and the butlers, none of us would be.”

Watch the clip below for other another sneak peek of the interview.

Oprah’s Next Chapter airs Sunday at 9/8C. Lee Daniels’ The Butler opens in theaters nationwide August 16.
