It's kind of amazing that the actual story came from Carl Reiner. It's cool that a TV legend isn't just a voice on the series, he's also pitching ideas.
"It breaks your heart. It is designed to break your heart. The game begins in the spring, when everything else begins again, and it blossoms in the summer, filling the afternoons and evenings, and then as soon as the chill rains come, it stops and leaves you to face the fall alone." --- Bart Giamatti, on baseball
The "super deluxe" version is slated for '08 sometime -- apparently Fincher wasn't finished with the extras in time for this release. It'll have Fincher's "Director's Cut" on it but (as of right now) NOT the theatrical version.
