MED HONDO'S epic film about an African sorceress-queen's repulsion of French troops in the 19th century, Sarraounia, will be shown for two days only at the Biograph this week. Hondo, a Mauritanian, adapted the film from a novel by Abdoulaye Mamani -- in turn based on real events in central Africa in 1898 -- and shot the film in Burkina Faso. Hondo interweaves legend with superb battle scenes. Along with Black and White in Color, it's one of the few movies about the colonization of Africa that acknowledges an African perspective. Hondo will attend the four screenings to answer audience questions. "Sarraounia" will be shown at 7 and 9:30 Wednesday and Thursday. Admission is $5. 333-2696.
