To my surprise, there have actually been a few movies filmed on Guam: Son of Godzilla (1967), No Man Is an Island (1962), and the most recent (straight to DVD) dismal failure: Max Havoc: Curse of the Dragon (2004) starring David Carradine and Carmen Electra.
Max Havoc was an unmitigated disaster that resulted in several lawsuits. Everyone associated with the film lost money, including the Government of Guam that lost $800,000. According to an L.A. Times article, the movie was a bomb from the beginning. "The crew worked 14 to 16 often chaotic hours a day mostly 'shooting people running up and down the hallways' of the luxury-class Outrigger Guam Resort hotel," adding, "I'll give you 20 dollars if you can watch 20 minutes."
Today a friend brought a new movie to my attention. Its an indie production shot on Guam last year. I watched the trailer online - the filtered yellow hue and tragic urban decay milieu gave it a gritty, depleted and sinister perspective more reminiscent of East L.A. than Guam. Frankly it was interesting recognizing many of the locations, yet I was totally unable to grasp any of the locations in the movie's ominous context. And nothing on Guam is ever that yellow, not even the school buses.
I also noticed that they filmed in the National Park - without a film permit!!!
