Any article with a "Soldier" banner covers a topic that appears in the film Soldier, which was written by David Peoples, co-writer of Blade Runner, and was referred to as a "sidequel" to Blade Runner by Paul W.S. Anderson, the director of Soldier. Additionally, Soldier's production designer and Blade Runner's art director, David L. Snyder, referred to Soldier as an "extension" and sibling film to Blade Runner. These are the reasons why Soldier is included on this Wiki. However, beyond these statements, it has not been officially recognized as a part of the Blade Runner franchise, this being the reason why the articles are separated from the film continuity.
