Original?

Apparently the Writer’s Guild of America has nominated Avatar for an award for Best Original Screenplay. This is surprising news. I had no idea Avatar even had a screenplay. I thought James Cameron had just organized a big game of charades and Sam Worthington took three hours to mime Ferngully before anyone in the cast or crew was able to guess it.

Also, for reference, here’s a definition of “original”:

Fresh, different, pioneering

I do not think it means what they think it means.
