The documentary footage is of the real Gary Ridgway confessing to the killings. The flashback of Ridgway's fictional "mentor," Boris, has a distinctly different look and atmosphere compared with the rest of the movie. That is because the footage was not shot by director Ulli Lommel but by
German actor-director "
Marian Dora," a pseudonym for the physician who began making gory horror films around the same time Lommel directed
Green River Killer. Dora made
Cannibal – Aus dem Tagebuch des Kannibalen, for example. Dora, who also worked on Lommel's
Zombie Nation, in this flashback directs actor Carsten Frank as he strangles a woman.
Green River Killer was the second in a series of direct-to-
DVD titles directed by Lommel and released by
Lions Gate Entertainment under its Artisan label. The first was
Zodiac Killer (2005).
Green River Killer would soon to be followed by
BTK Killer (2005) and
Killer Pickton (2005). Other direct-to-DVD movies directed by Lommel and featuring serial killers would follow in 2007 and 2008. Ridgway's home in the movie, which is a residence located in
Marina del Rey, California, was also the house inhabited by "Producer McCoon" in
Black Dahlia (2006). ==References==
