The characters played by David Carradine and Richard Roundtree were not included in the original screenplay, having only been added late in production to bolster the film's star power. Carradine and Roundtree filmed their scenes during a 10-day period in Los Angeles for which director Albert Pyun was not involved.
The Guam government sued producer John F.S. Laing after the film was finished, claiming he wrongfully convinced government officials to contribute $800,000 to help guarantee a production loan which was defaulted on. Laing denied this and counter-sued, claiming the government broke a promise of financial support and cost his company $1.5 million.
Lighting technician Elvin Ralph Coon III was very critical of the film in a Los Angeles Times article from 2007, claiming that "The whole thing was just bad all the way around . . . This thing was really destined to wind up in the cutout bin of some truck stop on the way to Barstow."
During production, workdays for the cast and crew frequently lasted as long as 16 hours.
