Yutani's declaration of "Shouryuken" before opening fire is a reference to the video game Street Fighter 2. It literally translates as "Rising Dragon Fist", and is the battle cry attached to an unstoppable uppercut move.
There are four different versions of the movie, one of 111 minutes (director's cut), the longest version of 128 minutes, and two versions of 85 minutes and 99 minutes (the latter marketed in North America).
After seeing this film, producer Peter Frankfurt chose Norringron to direct Blade.
The director himself was never satisfied with the final result before the premiere, making numerous edits of the film. In the end he made his own version.
Several characters are named after movie directors. "Jack Dante" is named after Joe Dante. "John Carpenter" is named after John Carpenter. "Scott Ridley" is named after Ridley Scott. "Weyland" and "Yutani" are named after the company in Alien (1979), directed by Scott. "Sam Raimi" is named after Sam Raimi. In one scene, Raimi fires a missile at the Warbeast. The succeeding shot where the camera follows the homing missile in fast-forward is a likely homage to Raimi's The Evil Dead (1981) where a similar filming technique portrays an unspecified evil charging through the woods.
