- Matt Damon turned down the lead role in Avatar and lost roughly 600 million dollars. James Cameron offered him 10 percent of the film’s profits to play Jake Sully. Unfortunately, Damon had to decline due to his commitment to the Bourne franchise, making it arguably the most expensive refusal in Hollywood history.
- Sam Worthington was living in his car before he got the part. The Australian actor was unknown internationally and had sold all his possessions for around 2,000 dollars. Consequently, his life changed overnight from homelessness to starring in the biggest movie of all time.
- Kate Winslet held her breath for seven minutes and fourteen seconds while filming. She smashed the previous Hollywood record held by Tom Cruise for Mission: Impossible. Amazingly, she achieved this feat to perform underwater scenes for The Way of Water without using scuba gear.
- The Na’vi language was built from scratch by a professional linguist. Paul Frommer created over a thousand words and specific grammar rules for the alien race. He specifically designed it to be pronounceable for actors but gave it a unique sound by removing hard consonants like “b” and “g”.
- James Cameron actually laughed at the famous Saturday Night Live sketch about the Papyrus font. Ryan Gosling starred in a viral skit mocking the movie’s logo for using a cheap, standard computer font. Years later, Cameron joked, “We are using Papyrus for everything now,” just to spite the critics.
- Visually, you can distinguish Avatars from real Na’vi by looking at their hands. The genetically engineered Avatars retain human DNA and have five fingers and eyebrows. In contrast, the native Na’vi people possess only four fingers and have no eyebrows at all.
- The production team used real dinosaur sounds from Jurassic Park. The screeches of the flying banshees and other Pandoran creatures are actually recycled audio stems of T-Rexes and raptors. Thus, the two biggest sci-fi franchises share the same DNA in their sound design.
- Sigourney Weaver’s character smoked cigarettes to make a specific point. James Cameron faced criticism for showing smoking in a futuristic movie. He defended the choice by explaining that Grace Augustine cared so little about her human body that she actively destroyed it.
- he entire film set for The Way of Water was completely vegan. James Cameron is a passionate environmentalist and banned all meat and dairy from the catering menu. He wanted the production’s footprint to match the eco-friendly message of the movie itself.
- Filming underwater required thousands of white balls floating on the surface. To prevent stage lights from interfering with the motion capture sensors below, the crew covered the water tank with plastic spheres. This allowed the actors to surface safely while keeping the lighting consistent.
- The Avatar script was written in 1994, fifteen years before the movie came out. Cameron wanted to film it immediately after Titanic but realized the CGI technology was not able to do it. He waited until he saw Gollum in The Lord of the Rings before he felt ready to start production.
- Zoe Saldana will likely be in her fifties by the time the final movie releases. She started the franchise in her twenties. Because of the massive gaps between sequels, playing Neytiri will effectively span her entire professional acting career.
- The mineral name Unobtainium is actually a real engineering term. Critics mocked the name for sounding lazy and silly. However, aerospace engineers have used the word for decades to describe any material that is perfect for an application but impossible to get.
- Cigarette lighters would not work on Pandora. The atmosphere contains too much carbon dioxide and not enough oxygen for a standard flame to ignite. Therefore, Jake Sully would have suffocated in minutes without his exopack mask.
- Finally, the bioluminescence was not just CGI magic. Designers painted physical props with ultraviolet paint and used UV lights on set. This practical effect helped the actors understand how the glowing forest would look in the final cut.
