District 9 director Neill Blomkamp is back with another political sci-fi thriller, Elysium, which opened in theaters this weekend. This time the class wars rage between the residents of ravaged planet earth and a luxurious space station. The space utopia frequently appears throughout science fiction — a symbol of progress, hope, and human curiosity. We don’t have to travel to the stars to enjoy futuristic architecture. There are plenty of bold, bizarre, contemporary buildings right here on earth that look like they belong on the set of a sci-fi movie. Here are 20 of them.
