Deborah L. Scott says she took inspiration from an unexpected Old Hollywood star for Oona Chaplin's character in "Avatar: Fire and Ash,"— Bette Davis. Referencing the 1950 classic “All About Eve,” Scott says: "It's like that famous Bette Davis movie where she comes in and says, 'Fasten your seatbelts, it's going to be a bumpy night.' She's so formidable, and at first, it was hard when Oona was doing her performance capture."
