In 1999, filmmaker James Cameron acquired a breathtaking 100-acre estate named Tranquillity Base, designed as a sustainable sanctuary. After 24 years of dedicated work, this magnificent 8,000 square foot residence showcases stunning Balinese and Indonesian décor. It also served as the creative hub for the 'Avatar' film scripts. Now, this coastal paradise is up for sale at an asking price of USD 33 million.
