'The Butler' trailer: Oprah Winfrey and Forest Whitaker serve a nation's presidents

Lee Daniels' latest, "The Butler," serves as a sweeping look at the Civil Rights movement in the United States as seen through the eyes of a White House butler. The first trailer for the movie has arrived, and its many, many cameos seem like they'll be the project's major selling point.

Forest Whitaker plays the movie's titular butler, a real-life person named Cecil Gaines. Oprah Winfrey portrays his wife, while David Oyelowo plays their son. Rounding out the cast are Robin Williams and Melissa Leo as Dwight and Mamie Eisenhower, James Marsden and Minka Kelly as John F. and Jackie Kennedy, John Cusack as Richard Nixon, Alan Rickman and Jane Fonda as Ronald and Nancy Reagan, Liev Schreiber as Lyndon B. Johnson and Mariah Carey as Hattie Pearl -- and that's just scratching the surface of the people involved.

"The Butler" is due in theaters on Oct. 18. It will be interesting to see if future trailers and promotional materials play up the impressive cast as much as this trailer did. Here's the film's official synopsis:

"The Butler" tells the story of a White House butler who served eight American presidents over three decades. The film traces the dramatic changes that swept American society during this time, from the civil rights movement to Vietnam and beyond, and how those changes affected this man's life and family.
