Filmmaker James Cameron started pre-production of "Avatar: The Way of Water" in 2014. Though sequels two and three to the 2009 "Avatar" had been greenlit by then 20th Century Fox head Jim Gianopulos, Cameron knew change was coming. In early 2019, The Walt Disney Company acquired the studio and with it, Cameron's latest project. In the first installment of a two-part conversation with Cameron, the filmmaker shares what changes affected the production of the movie, and why what he calls an "arranged marriage" with Disney turned out better than expected. He also discusses the importance of theaters and repeat views for the film's success, and how he views streaming services.
