In an online interview, Gary Daniels claimed that his onscreen fight with Steven Seagal was originally conceived as much longer and showier by stunt coordinator Steve Griffin. Seagal supposedly choreographed the fight himself on the day it was filmed, rendering it much shorter and one-sided.
Steven Seagal and Anthony Hickox disagreed on much of the film which eventually resulted in Seagal leaving the film.
The hostility between Seagal and Canadian actor William Hope was very real. It started when Hope was approached by people in Bulgaria asking for autographs due to Hope being in the classic Aliens, while Seagal was completely ignored and made fun of. Seagal started to use every little thing to torment Hope, including complaining that Hope was feeding stray cats on set, which was an admirable thing, but not for Seagal, who complained that cats were giving him allergy. Crew members then mixed cat feces with Seagal's meals every opportunity, in short amounts so he wouldn't notice, and for the rest of the shooting, he ate food mixed with cat feces and urine, and never once noticed or complained.
One of the first films where Steven Seagal showed significant weight gain. In a Uruguayan press kit for the straight to video release of this movie, when it premiered at the local video store, Seagal is described as "His appearance is akin to that of the Butterball, a cenobite enemy from the film Hellraiser".
This is the second time Vinnie Jones and P.H. Moriarty have appeared together; the first was Lock, Stock and Two Smoking Barrels (1998).
