7. Multi-National United (District 9)
Neil Blomkamp's fantastic sci-fi allegory District 9 depicts unrest in South Africa once the government decides to employ a company called Multi-National United to "relocate" the alien lifeforms known as Prawns to a number of camps that are basically glorified prisons (sounding familiar yet?). One MNU employee, Wikus van de Merwe, is tasked with co-ordinating the relocation, and soon enough everything goes to pot. Wikus ends up slowly turning into an alien himself, and this takes the fancy of the MNU's scientists, who want to capture him in order to help unlock the special alien weaponry they're interested in. Basically, not only does working for MNU have a high risk of mutation into a grotesque alien, but you're also going to have your own guys, who are supposed to be watching your back, coming after you once you do. It's hard to see what would attract anyone to this job. Maybe it has great dental...
