I'm wondering what the merchandising teams are making of this film. Computer game programmers are probably rubbing their hands with glee - the action sequences in the second half are just a few steps away from being a first-person shooter, complete with alien weaponry and vehicles. On the other hand cuddly toy manufacturers may have to work a little harder on the Prawn image. However where there's a rand there's a way, and I look forward to seeing District-9 branded catfood on the supermarket shelf any day now.
This brings me to another point - over the years Hollywood has been accused of being run by Jews, gays, Freemasons, the FBI, the mafia, the popcorn lobby and even (heaven help us) actors. But in 2009 the true rulers of the universe have been subtly showing their paw through science fiction. Catfood plays a key role in District 9. The haunting landscapes of Moon were filmed in a giant cat litter tray. Coincidence? You decide.
