Two basic versions exist of Albert Pyun's action/horror hybrid "Adrenalin".The US version (R-Rated) and an Extended Version, which has been released in France, among other countries (I used the German DVD for the comparison). Aside from the Extended Version having more plot scenes bot versions also differ in regard to other aspects. Either version has a different score on several occasions. Furthermore the US version looks more "B-movie"-ish, it uses as color filter (most of all more blue) and presents more color and a more "dirty" look. Some special sound effects also create that impression. The Extended Version presents more natural colors and often uses more discreet sound effects.
