Roger Dean has filed legal action at a court in New York, alleging Cameron copied his ideas for the 3D blockbuster, which went on to become the highest-grossing film of all time.
Dean, who has designed album covers for bands including Yes and Asia, accused Cameron of "wilful and deliberate copying, dissemination and exploitation" of his imagery and claims the Oscar winner "studied and referenced his art in preparation for the film."
His complaint states, "The similarities of each such work are substantial, continuing, and direct so as to rule out any accidental copying or similarity in scenes common to the genre."
It is the latest legal hurdle for Cameron, who has been plagued by a slew of similar allegations since Avatar's premiere in 2009 - in December, 2011, he was hit with a $2.5 billion copyright lawsuit by a sci-fi screenwriter, while another plaintiff also filed copyright infringement papers against the moviemaker.
In February, a U.S. judge threw out a copyright lawsuit from artist Gerald Morawski, who claimed his paintings inspired the $2.78 billion-grossing movie.
After the victory, Cameron insisted, "It is a sad reality of our business that whenever there is a successful film, people come out of the woodwork claiming that their ideas were used. Avatar was my most personal film, drawing upon themes and concepts that I had been exploring for decades. I am grateful that the court saw through the blatant falsity of Mr. Morawski's claim."
Hardly ever is there any mention of Poul Anderson's 1957 story 'Call Me Joe'. There are some very similar aspects of Avatar and 'Call Me Joe'. A paraplegic connected to a false body through a machine that eventually transfers himself to the new fully functional body. This story probably has more basis for the movie, and probably pre-dates most of the other claims, than most of the others. Cameron is old enough that he probably read the story or someone related it to him when he was younger and he is using those memories. I guess once a story or idea gets old it becomes less recognized or is hopefully forgotten. The original story is not that long and considering the time period it was written it still is an interesting read. There was relatively little known about Jupiter, where the story takes place, and would not be relevant today. Search for the story online and read it. It won't ruin Avatar as a movie but see if your opinion is changed even a little about the connection.
