After it became the highest grossing movie of all time, director James Cameron decided that he was going to devote himself to making nothing except sequels to Avatar for the rest of the 2010s.
Composer James Horner, who worked with Cameron on the first Avatar movie in 2009 as well as on Aliens and Titanic said that the director is trying to condense screenplays for four sequels into three so he can fit them into the planned release schedule.
