Marcus Bagwell was so dedicated to the role of "The Warrior" that he lived the part 24/7 while shooting. In fact, he even remained in character up to and including the premier, only answering to The Warrior. His tag team partner from WCW, Scotty Riggs, cashed in a favour with Bagwell who got him some minor stunt work on the film. Riggs had to be excused from his stunt duties as he had lost depth perception due to his prolonged use of an eye patch. In order to use the name "The Warrior" Marcus Bagwell attempted to convince the WCW wrestler The Warrior (formerly the Ultimate Warrior) to allow Bagwell to take over the name. He refused but Bagwell used it anyways. Bagwell had suggested to Sidaris that he have a larger role and even rewrote a 150 page draft of a new script. Sidaris rejected his script due to its lack of gratuitous shots of planes taking off and landing. Bagwell wrote the scripts for a prequel trilogy but Sidaris unfortunately was forced to retire due to diminishing health. At his eulogy it was stated that one of his biggest regrets was not working more with Marcus Bagwell.
At the L.E.T.H.A.L. safe house, there's posters of Savage Beach (1989), Do or Die (1991) and Hard Hunted (1992).
Co-stars Kevin Eastman, co-creator of the Teenage Mutant Ninja Turtles, and Julie Strain, Queen of the B-Movies, were married from 1995 to 2006. They would both appear again in the next and final LETHAL movie, Return to Savage Beach (1998).
According to series creator / director Andy Sidaris, it was Julie Strain's idea on what she should wear - a thong workout piece - on her initial scene in the office while having a meeting.
