Star Wars : Darth Bane (Fan-Trailer)
This trailer uses clips from a number of movies, it was made for fun. Basically its the short version of Rise of the Fallen Empire but it reveals one of the alternate plots in the story, the rebirth of Darth Bane! Darth Bane is arguably one of the most powerful (if not the most) and influential Sith Lords ever to live in the expanded universe. Vin Diesel as Riddick with a light saber is the closest match in existing cinema that I could find so for now it will have to do.
Before writing messages revealing this video being a "FAKE" know that the title and description reveal that yes this is a FAKE and by saying it in a comment you are not enlightining anyone! Thank you
