In case you missed it, there was this small little movie that came out last year called Avatar. (Not to be confused with Avatar: The Last Airbender.) It really struggled; only pulling in three Academy Awards. (So sad.)
Apparently, he is hoping this re-release will test out whether or not the Avatar brand can develop into a Star Wars- or Star Trek-type franchise.
Perhaps, being an old fart Star Wars fan, I find this difficult to believe. But stranger things have happened. (As in back in 1977.) And even an attempt at doing more with the Avatar franchise will make at least the Avatarians (Pandorians? Avatar fans?) happy, for now. So more power to him.
