In the last few days there has been multiple reports that the writer for this project will be Aaron Sorkin. Sorkin is known for his work on NBC's The West Wing and Studio 60 (which was recently canceled).
This is very interesting, strange and exciting news. If they are actually going to go through with this, they really need to do it right. If they keep Wayne Coyne involved with the project, I'm sure justice will be served to the artistic concept of the production.
Sadly, still no word on the release of the feature film Christmas on Mars which has been rumored to be released since Christmas 2003.
