 The documentary uses 3 main styles, jumping from one to the other.One style is the use of actors to represent certain key events or circumstances.A second style is the plain explanation of the things taking place (which could be done by a narrating voice and visual gags, by the presenters in some modern day location, or by the presenters at a representation of an event), and a third style was some limited interaction of the presenters with the historical characters portrayed or the social circumstances depicted.
