Duality is a Star Wars fan film created by Mark Thomas and Dave Macomber that made its debut on the internet on February 10, 2001. It is one of the first fan films to exclusively use bluescreen footage composited onto virtual backgrounds.
During their honeymoon, Macomber and Thomas originally produced Duel as an actingchoreography demo for an actor, but felt they could make a better film with CG stages, as opposed to the location work on the original. The cast consists of three actors, two of whom are the creators.The script was first written by Thomas, with Macomber devising the fight.
