Check out the following concept art for an Alien movie that Neill Blomkamp was developing.
Blomkamp posted the images on Instagram with mention this was just a side project of his and nothing to do with any movie studio.
It's possible Blomkamp, the director behind District 9, Elysium and the upcoming Chappie film, may have intended to use the art as a pitch to Fox for a new Alien flick.
Updated: with two more pieces of art. In addition, Blomkamp makes note that maybe he will go back to it.
