Little Miss Sunshine
I was happy to see Michael Arndt win the Oscar for best original screenplay for Little Miss Sunshine as it's a hell of a great movie, a true ensemble comedy where every character counts and contributes and is uniquely drawn. Like many, I was surprised that Alan Arkin won for best supporting actor, not because he wasn't deserving, he was, but because in the movie he is just one in a bus full of interesting souls. But good for him!

If you are into reading screenplays, and who isn't, you can find the Little Miss Sunshine script at simplyscripts.com. They also have the best adapted screenplay, The Departed, a movie I haven't seen yet but want to (there's a long list!). If you'd like to know more about Michael Arndt and his battles to get his movie made I'd suggest subscribing to the free podcasts at creativescreenwriting.com. They currently have two interviews with Arndt, and of course interviews with many other screenwriters and directors.
