There were 2 different versions of this film made for different markets. The first version was a straight forward action film, which was made for the US market (to get an R certificate) and for countries like the UK where censorship restrictions where problematic. However the director filmed several additional extra gory scenes for use in Italy, Japan and other countries that demanded a "stronger" version. These included alternate takes on the intro fight scene, the drug house massacre and the raid on the jungle camp, which featured additional violence nudity and gore. The US DVD by Anchor Bay is of the extra gory version, however the extra gore scenes are presented in Italian language with English sub-titles. They claim that the the extra-gory version was never dubbed into English (actually the whole film was primarily shot in English in "live" sound recording), however the Hong Kong VCD of this version was presented in English, indicating that full English language prints of this version did exist.
