Did you like The President with Douglas and Sheen?
The screenplay he wrote was soooo long for a movie that he had a lot of developed ideas left over for The West Wing.
I even got his first series "Sports Night" (2 Seasons) which has less to do with sports and more about behind the scenes issues.
Also check out Studio 60 if you have not yet. Especially if you like classic era Saturday Night Live.
The American President was awesome, with Douglas, Sheen and Michael J Fox. Of course Benning did her part as well.
I've never seen sport night or Studio 60. It wasn't until West Wing ended that I started to realize how much Sorkin material was out there. I'll check out Studio 60 definitely.
