Kevin Costner is bringing his epic historical film "Dances With Wolves," in which he stars and makes his directorial debut, here next month for a world premiere in connection with the Smithsonian Institution. The Costner film, which was shot in the Great Plains of South Dakota with an authenticity that has the Native American characters speaking the Lakota language (subtitles are used), will open Oct. 19 with a gala evening at the Uptown Theatre. It will benefit the National Museum of the American Indian and the Smithsonian's Resident Associate Program. A reception afterward at the Sequoia restaurant at Washington Harbour will feature such Native American foods as venison and smoked turkey. A Lakota (Sioux) ceremony honoring Costner for his authentic portrayal of Lakota life is planned for the reception.
