What is it about?
This is how Wikipedia describes this animated movie:
Underworld: Endless War is 2011 animated film and a collection of three short, tie-in stories whose creation was supervised by Len Wiseman, director of the first two Underworld films.
Each film tells a different story, and at different periods of history, to highlight new events of the Underworld mythology.
These stories also tell of what happened before the events in Underworld: Awakening (2012).
These shorts were released on December 20, 2011, as a part of the new Underworld Trilogy: The Essential Collection of Underworld, on Blu-ray.
Each episode is a little over five-minutes long.
