I picked up a $2 book of 1950's short stories. Was reading one by Poul Anderson written in 1957 called "Call Me Joe" and realised I was reading the script for Avatar!
I googled and see that many think Cameron has ripped off this short story for his film. For example:

Anyone else here read the novella and also noticed the similarities?
