The German dubbing of this film, although changing a lot of the political issues of the story, is partly regarded as cult especially due to lines like "Das ganze Gehirn weggelutscht" ("They sucked his brains out") as performed by Joachim Kerzel.
The fort defense scene contains many references to Zulu (1964): "We're all gonna die!", "Fire at will" and "Fall back into the compound", along with some similar camera angles.

A miniature Millenium Falcon can be seen on the backside of one of the starships' bridges.
Most of the arachnids appearing on film are CGI but a few life-sized, robotic models were built. However, during the battle scenes, the actors wound up looking at director Paul Verhoeven himself who would stand in front of them and jump and scream to elicit their reactions.

The movie, instead of an elite fighting force equipped with Powered Suits, they are a conventional army armed with conventional weapons - but apparently without armored vehicles, artillery, most heavy weapons, and other vital equipment.
In the movie credits, Amy Smart's character is identified as "Pilot Cadet". However, the FedNet announcer refers to her as "Lieutenant Stack Lumbrezer" - (which is likely) an homage to one of the movie's co-producers, Stacy Lumbrezer. .
