As Cecil Gaines, Whitaker plays the man who served under eight presidents across three decades as the White House's butler. Winfrey stars as his wife, and, in the clip above, Mr. and Mrs. Gaines teach their son, whom they haven't seen in seven years, a lesson about respect, breaking down barriers, and the great Sidney Poitier.
The movie also stars Terrence Howard, Matthew McConaughey, Jane Fonda, and many more.
Watch Winfrey and Whitaker in action above. "The Butler" hits theaters Aug. 16.
