Wikus Van De Merwe: This whole's thing's under your shack? For 20 years, you've had this fookin' thing hidden out here? This is, this is very illegal, I mean, this is... This is a fine.
Trivia: The topic of xenophobia runs strongly throughout the film. This is a very real issue for South Africa as evidenced by the xenophobic violence in early 2008 where approx. 30 foreigners living in South Africa were murdered and hundreds left injured and/or destitute. In fact there are still displaced foreigners living in homeless shelters, churches, etc today.
Question: Is there ever an explanation given as to why the Aliens visited Earth in the first place?





Answer: Yes. They weren't intending to visit Earth at all, but their ship became crippled somehow and they were all slowly dying. They made their way to Earth looking for help.
