Comparison between the German FSK 16 VHS by Empire and the PG-13 DVD by New Line Home Entertainment (Director's Cut).
21 cuts = 4 minutes and 4 seconds.
"The Guyver" originally was an '80s anime series, produced in Japan. Due to the great success, also in the USA, it was decided to turn the series into an American live action movie, which resulted in a mix of action, science fiction and trash with some decent effects, created by FX artist "Screaming Mad George", who was also responsible for the direction, together with Steve Wang. This was the first and also the last movie that was directed by Mad George, while Steve Wang came back to the director's chair a few years later for the sequel "Guyver - Dark Hero". By the way, the movie was produced by Brian Yuzna (Return of the living Dead 3 / Bride of Re-Animator).
Regarding the releases, it seems that a completely uncut version is hard to get, because the only versions available in the USA, as well as in the UK and Germany, are cut versions.
Some story scenes in the first half of the movie were shortened in the German FSK 16 version. But this is actually not that unfortunate, because mostly it's just some shots that were cut by a few seconds. Hardly any of them was cut by more than 10 seconds. What's more important is that all of the few bloody effects still remained in the movie. These effects had to be cut in the US version, called "Director's Cut", in order to get a PG-13 rating, but the story scenes which are missing in the German version are contained in there. The British BBFC 15 VHS also lacks these story scenes, just like the German version, but it's not completely clear whether additional cuts were made or not; there's no entry in the BBFC database.
Only the PG-13 version has a text display at the beginning. A narrator is speaking.
The titles differ in the two versions: PG-13: Guyver / FSK 16: Mutronics.
