Five crew members were killed in a helicopter accident during filming. The film is dedicated in their memory. They were: Jojo Imperiale (pilot), Geoff Brewer (stuntman/Actor: Maj. Anderson), Gadi Danzig (cameraman), Mike Graham (key grip) & Don Marshall (gaffer).
Lee Marvin was attached to reprise his role from the first film (The Delta Force (1986). However, his health had already been declining when he made that film, and he died in 1987.
When the accident occurred that ended up claiming the lives of several crew members, Chuck Norris and his brother Aaron Norris gave blood at the hospital to try and save them.
The script that was filmed was a greatly pared-down and smaller version of what was originally planned. Cash-strapped Cannon Films could not afford the original draft.
