Are you referring to Open Hearts ?
On imdb.com Braff declared: "There is always pressure, but I'm going to do something that isn't anything like Garden State. "The next thing I will do will be completely different, Open Hearts, which is a Danish movie that I adapted. "It's a really dark drama about a car accident and the way the accident affects all the people involved in it. I was going to do it this summer, but since I couldn't get my top people I'm waiting until next summer."4 sept 2006
Don't know much about Braff's stuffs, but I remember he did Garden State and Last Kiss being still in the cast of Scrubs. And the 7th season was, in the beginning, the last one, after writers'strike and NBC trouble was planned the 8th season and he signed about. But I cannot have infos about these stories, have only red somewhere, in case of a 9th season, both Bill Lawrence and Braff would give up. But...who knows...
Anyway, I agree, Scrubs without JD and the usual main cast would be weird.
