Trivia: In the scene where Wells asks Cooper to knock him out, Kevin McKidd throws a stage punch the first time, but misjudges the distance of the second and catches Sean Pertwee on the nose. Pertwee didn't feel the punch however as he really was drunk for that scene. This is all talked through on the DVD.
Trivia: This film was set in Scotland but filmed in Luxembourg all apart from the shots filmed from helicopters, which are in fact scenes of Scotland.
Trivia: After Sarge and Cooper break through the floor into the kitchen, Sarge retrieves his watch from the dismembered corpse of Witherspoon ("Spoon"). Cooper asks where Spoon is and the Sarge replies "There is no Spoon". A clear reference to the famous line from the original "Matrix". (01:32:30)
