Ninja claims that they painted the lair in "Chappie" themselves.

Neill Blomkamp’s 2015 sci-fi film “Chappie,” about an artificially intelligent law enforcement robot captured by a group of gangsters, starred Hugh Jackman, Sigourney Weaver, Hugh Jackman and notably the rap duo Die Antwoord, comprised of Ninja and Yolandi Visser, who appeared as themselves. In the film, the duo had their own lair where they kept and “raised” Chappie, the robot, to be one of their own. Now, Ninja claims in an Instagram post that they painted the lair themselves and were never credited for their work.

He concludes by saying that the duo plans to make their own movie soon “wid no brakes on.” Check out the post below.
