District 9 and Avatar are extraordinarily alike: both released in 2009, they tell a very similar story (even if they frequently invert the value signs). One would think that the scriptwriters have collaborated in some way. The first section of this paper analyses comparatively the two movies and identifies their common interests and a multiplicity of crucial differences. This comparison registers an extraordinary thematic and narrative convergence as a premise for the argument that is presented in the second section: in spite of their different approaches both movies present inherently settler colonial stories.
