Avatar is a 2009 Americanepic science fiction film written and directed by James Cameron, and starring Sam Worthington, Zoe Saldana, Stephen Lang, Michelle Rodriguez, Joel David Moore, Giovanni Ribisi and Sigourney Weaver. The film is set in the mid-22nd century, when humans are mining a precious mineral called unobtanium on Pandora, a lush moon of a gas giant in the Alpha Centauri star system.The expansion of the mining colony threatens the continued existence of a local tribe of Na'vi—a humanoid species indigenous to Pandora. The film's title refers to the genetically engineered Na'vi-human hybrid bodies used by a team of researchers to interact with the natives of Pandora. When his brother is killed in a robbery, paraplegic Marine Jake Sully decides to take his place in a mission on the distant world of Pandora. There he learns of greedy corporate figurehead Parker Selfridge's intentions of driving off the native humanoid "Na'vi" in order to mine for the precious material scattered throughout their rich woodland. In exchange for the spinal surgery that will fix his legs, Jake gathers intel for the cooperating military unit spearheaded by gung-ho Colonel Quaritch, while simultaneously attempting to infiltrate the Na'vi people with the use of an "avatar" identity. While Jake begins to bond with the native tribe and quickly falls in love with the beautiful alien Neytiri, the restless Colonel moves forward with his ruthless extermination tactics, forcing the soldier to take a stand - and fight back in an epic battle for the fate of Pandora.

Aliens of the Deep is a 2005 documentary film, directed in part by James Cameron and filmed in the IMAX 3D format. It was produced by Walden Media and Buena Vista Pictures. Cameron teams with NASA scientists to explore the Mid-Ocean Ridges, submerged chains of mountains in the Atlantic and Pacific oceans that are home to some of the planet's more unusual forms of life. Cameron joins up aboard the Russian research vessel Akademik Mstislav Keldysh with a group of NASA scientists, as well as some American marine biologists, to investigate ten hydrothermal vents in both the Atlantic and Pacific. The vents have their own unique ecosystem, which support diverse organisms such as giant tube worms, swarms of blind white crabs, and vast amounts of shrimp which are capable of "seeing" water that is heated by the vents. These creatures do not require sunlight like other organisms, and instead obtain their energy from the vents. They are able to survive in the superheated and sulfurous water. Because of this, the documentary suggests that this is what life beyond Earth might look like. As some alien ecosystems are likely to be a lot harsher than a typical terrestrial ecosystem, these exotic vents provide an insight into some of the forms that alien life might take.
