Oh, and in 3D, too.

The director behind the first two Chronicles of Narnia films and the first two Shrek films has another live-action/CGI hybrid in development. Variety reports that Lightstream Pictures has preemptively picked up Andrew Adamson's fantasy pitch Fountain City and set the helmer to lead the production from a screenplay by his writing partner Joby Harold.
Lightstream is co-financing the film which is reportedly projected to be around $100 million.
For now, the company is keeping the plot line under wraps.
Adamson, Aaron Warner, Tory Tunnell and Lightstream executives Garrett Kelleher, Paul Currie and Lawrence Inglee will produce.
There is no way to tell anything about this so until more detail is revealed it is a wait and see.
Though I bet there is a city with a fountain in the story.l
Unless it's about a fountain soda machine. There is that possibility....
I'm guessing it probably involves some adults who have screwed everything up, and a group of children and/or teens who have to fix everything.
