I found Nintendo's description of it, located
here.
"In this simulation game, players try to build and control their own Hollywood motion picture studios. You can create unique movies, choosing everything from the script, cast, crew, lighting, sound and budget to the marketing, the money, and the sequel. Hey, you might even get to toss around words like "montage" and "participation."
This game is in pre-production. We'll have more information as it develops.
Release Date Q4 2004"
I doubt its going to be released by the end of this year. I haven't heard much about it.
