Trivia, insights & behind the scenes
Cryptosporidium is real and caused a massive Milwaukee outbreak in 1993, making this accidentally topical for 1998 cable.
This aired during the peak of TV disaster movies competing with theatrical blockbusters—note how it rips off Outbreak's 'outsider scientist' structure on a budget that couldn't afford a monkey.
