James Cameron is being sued again for allegedly ripping the idea for Avatar, and this time for a sum to the tune of about $2.5 billion. Apparently, it's really hard to be original when you're writing a movie about blue aliens, because everyone else has had that idea before too!
Bryant Moore is the plaintiff this time, a little-known science fiction writer. He claims that Cameron used his two screenplays, Aquatica and Descendents: The Pollination as the basis for Avatar. According to TMZ, Moore points out similarities between the screenplays and the film in the lawsuit, such as, "bioluminescent flora/plant life, unbreathable atmospheres, matriarch support of hero vs. heroine, spiritual connections to environment and reincarnation, appearance of mist in scene, sunlight to moonlight, crackling from gargantuan foliage, blue skin/green skin and battle scene on limbs/branches."
In addition to suing Cameron, Moore is suing 20th Century Fox, as well as Cameron's production company.
