James Cameron is about to spend the next eight years immersed in the world of Pandora creating four Avatar sequels, which, considering they just cast Cliff Curtis in a major role in said sequels, means it looks like these Avatar follow-ups are actually finally happening after nearly a decade of development. Cameron himself is no stranger to sequels having started his entire directorial career with Pirhana 2: The Spawning, a cheapie 1981 horror movie he directed with Ovidio G. Assonitis. A decade later he would helm Terminator 2: Judgement Day which is widely considered to be one of the best blockbusters of the 1990's. In between those two sequels though came Aliens, a direct follow-up to Ridley Scott's earlier Alien film.
