If you're planning to attend the Seventh Annual Black Diaspora Film Festival, prepare yourself to have a hard time picking among an enormous variety of offerings. The films being screened at the North Carolina Mutual Life Insurance building for the Feb. 9-18 event range from Buck and The Preacher, Sidney Poitier's first feature as a director, to John Sayles' Brother From Another Planet to short documentaries on cultural figures like Dorothy West and Colin Powell. Some days have definite themes: Saturday, Feb. 10, chronicles black history through movies like Buffalo Soldiers, Don't Leave Out the Cowboys (Nat Love pictured) and Glory and Honor, about African-American explorer Mathew Henson, who conquered the North Pole along with Commander Robert E. Peary, but never got credit because of his race. Sunday, Feb. 11, looks at heroes--Rosa Parks, George Washington Carver, Charles Drew. The following weekend also has a stellar line-up, all of the films falling under the rubric of this year's theme: "Bold, Black Adventure: Films of Excitement and Exploration."
