Below news from this GeekTyrant article:
There’s hardly anything that’s been revealed for Neill Blomkamp’s next film Chappie. He’s not saying anything. At this point, all we know is that it’s a sci-fi comedy that centers on a “really ridiculous robot.” It will also be shot in the same visual style as his other films that include District 9 and his upcoming movie Elysium.
It was also recently revealed that the South African rap-rave group Die Antwoord are going to be in the film, and that they will play themselves. I don’t know if you are familiar with the group or not, but they fit right in with Blomkamp’s style.
The above link also includes one of Die Antwoord’s (inappropriate for children) videos. Ha! I don’t really know what to think… But I do love District 9.
