Tv titan Oprah Winfrey is set to pull in thousands of dollars for charity by auctioning a meeting with her at the upcoming premiere of The Butler.

The highest bidder in the CharityBuzz.com auction will be introduced to the talk show queen at either the film's New York City premiere on 5 August (13) or the Los Angeles debut on 12 August (13).

Winfrey, who plays the wife of presidential butler Eugene Allen in the movie, is due to attend both events with her castmates Forest Whitaker, who stars in the title role, and Robin Williams, who plays Dwight Eisenhower, as well as Alan Rickman and Jane Fonda, who portray President Ronald Reagan and First Lady Nancy.

The lot is expected to fetch $25,000 (£16,129) for the La Jolla Playhouse theatre group in San Diego, California.
