'Boxhead' Robots they get called and yea, looks like Neill Blomkamp likes the style in his films, if your a Gamer check out 'Titanfall' its full of imagery that wouldn't be out of place in one of his films.. He is a fan of it and i often wonder if he would make a film of it which would be great!..

Reason they're similar is because the same people are involved in making the movies

I think they look pretty different .
