Documentarian Alex Pritz didn\u2019t have a background in film. He studied environmental science in college and was certain he wanted to be a scientist to \u201cwork on these big problems plaguing our planet,\u201d he says.\xa0But at the end of his time at university, he realized that film was a better way to engage with big issues. \u201cI have always been interested in participatory video working with communities that are experiencing conflicts and challenges to help them use film as a method of advocacy and also self expression,\u201d he remarks.\xa0With that approach in mind, he went to the western part of Brazil\u2019s Amazon rainforest to direct \u201cThe Territory.\u201d The filmmaker discusses how he was introduced to the Uru-eu-wau-wau people, a small indigenous community that is fighting to protect their land, the challenges and accessibility issues he faced to make the documentary. But first Kim Masters and Matt Belloni look into the competition between Amazon and HBO for more viewers. Which series will win: \u2018The Rings of Power\u2019 or \u2018House of the Dragon?\u2019
