Still trying to find that damn article, but this link kind of shows what I referencing to James Cameron & Fox pictures saying "We own the AVATAR movie title". This is why you double check your sources before talking, I forgot how long Cameron was working on this project, 11 years or more, I hope its worth the wait.

I will say this, some times it best never to have 2 films with the same title, for example "Employee of the Month".......
