and Roberts leave the doctor's home, police arrest them. Scott and GR76 ambush the police convoy. After a chase, the police bus and the UniSol truck both drive off a cliff and explode, killing GR76. Deveraux and Roberts head to Deveraux's family farm in Louisiana. After Deveraux is reunited with his parents, Scott appears and takes the family and Roberts hostage. Scott's use of muscle enhancers enables him to mercilessly beat Deveraux. Roberts escapes, only to be seemingly killed by a grenade thrown by Scott. Deveraux grabs the muscle enhancers Scott used and injects himself. Now evenly matched, Deveraux impales Scott on the spikes of a hay harvester and activates it. Roberts, who survived the explosion, embraces Deveraux. Cast Production In February 1990, Andrew Davis was hired to direct, and he also contributed to the screenplay. He was later replaced by Roland Emmerich, who brought on his creative partner Dean Devlin to rewrite aspects of the script. Principal photography began in August 1991. Carolco, the company that produced the film, was having financial troubles and hoped that the film's box-office return would keep them afloat. Release Marketing At the 1992 Cannes Film Festival, Van Damme and Lundgren were involved in a verbal altercation that almost turned physical when both men pushed each other, only to be separated. On his website, Lundgren confirmed that it was just a publicity stunt to promote the film. It was the last film that used the multichannel surround-sound format, Cinema Digital Sound. Alternative ending The Special Edition DVD release features an alternative ending, which starts shortly after Scott takes Deveraux's family and Roberts hostage. As Deveraux grabs a shotgun in the kitchen, the front door opens, and he sees his mother at the door before Scott shoots her to death.

Shortly after grinding Scott to death, Deveraux is shot by his father before Dr. Christopher Gregor and his men appear. Gregor explains that he used Deveraux to entrap both Scott and him, and that Deveraux was staying with people posing as his parents. He then has his men shoot Deveraux, but before Deveraux dies, the police and Roberts' news crew arrive. The news crew douses Deveraux with a fire extinguisher to stabilize him while Dr. Gregor and his men are arrested. Roberts is given the microphone to cover the arrest,
