The team from MainStay Productions usually takes over different parts in their movies: John Lyde is for example also one of General Drennon's guards and plays the shadow agent during the fight scenes. Paul D. Hunt is also a guard, and together with Danielle Chuchran the trio practiced that fight at home. The same holds for John Lyde, Danielle Chuchran and Adam Abram in Fangtor's fight. Here Danielle Chuchran also helped editing that scene ... etc.
The first scene (Nemyt vs Fangtor) was done as a concept for a possible series or movie. It was shot beginning of 2012, while the rest of the film was taken later in August. Nemyt's costume is different, and Danielle Chuchran looks more adult.
