Context paragraphs:
Guimba the Tyrant: Guimba the Tyrant (French: "Guimba, un tyran, une époque" ) is a 1995 Malian comedy drama film in the Bambara language (with some Fula language components), directed by noted Malian director Cheick Oumar Sissoko.  The movie shows the rise and fall of a cruel and despotic village chief "Guimba", and his son "Jangine" in a fictional village in the Sahel of Mali.  Some of the storytelling was done through the medium of the village griot, and with the film being placed in an old setting, lends an epic touch to the movie.  The exact chronological setting of the movie is difficult to ascertain, being set in an isolated village, but the commonly used weaponry shown is the blunderbuss (however one scene outside the village features a neem tree, a species introduced to Africa during the colonial period).  The film depicts some magical components, including a solar eclipse brought on by magic.  Casting was only partially done from among professional actors.
