Screenwriter Joe Halpin is quoted in the book "Seagalogy: The Ass Kicking Films of Steven Seagal" as saying that "Attack Force" had originally been written and filmed as "Harvester," a sci-fi/horror movie with Steven Seagal and his men battling an invading force of vampire space aliens. After Seagal, Halpin and director Michael Keusch had delivered the finished sci-fi film, the production and distribution company decided to eliminate the sci-fi space-alien elements and replace them with another plot about a super-addictive drug that turns its users into superhuman killers. They called back a few of the lower-paid actors for re-shoots, re-dubbed the majority of Seagal's dialog via ADR, totally re-edited the film and changed it into "Attack Force" as it is now known. Seagal and Halpin were not involved.
Steven Seagal retroactively dedicated his performance in this film to the puppy he accidentally ran over in Arizonia.
Last screen appearance of Lisa Lovbrand as of 2021.
