Preparing for what is sure to be a much talked-about film, the stars of Lee Daniels' "The Butler" attended a press conference at the Waldorf Astoria Hotel in New York City on Monday (August 5).

Enjoying a return to the big screen now that her daily talk show is over, Oprah Winfrey wore a gray top and matching slacks as she smiled brightly for photos.

Coming so far from "Glitter," Mariah Carey looked lovely in a short black dress with lacy sleeves while the rugged Liev Schreiber wore a classy black suit with a white dress shirt opened at the neck.

Looking cute as a button, Minka Kelly donned a blue and white floral dress with blue strappy heels, befitting her role as First Lady Jackie Kennedy.

Hitting theaters on August 16th, "The Butler" follows an African-American who eyewitnesses notable events of the 20th century during his tenure as a White House butler.
