Police chief Bruges tells Van Damme the decision to act was GIGN's move, not his. GIGN (Groupe d'Intervention de la Gendarmerie Nationale - French SWAT) exists in France but not in Belgium where the movie story takes place. In Belgium, police's tactical unit is called ESI (Escadron Special d'Intervention).

In the court room the attorney says, "How does this actor play Death? Let me count the ways: mangled under the wheels of a truck, strangulation, fracturing the skull, taking out the tibula..."
