The idea was apparently hatched at a Sarah Marshall table read, where Hill and Brand exhibited a surprising chemistry. They only had a few scenes together in that film, and since I thought Hill's character was generally a weak spot, I spent most of those scenes being mildly annoyed. But I've seen Superbad, so I know that Hill has the funny, and Brand, whom I had never heard of before Sarah Marshall, has some of the movie's biggest laughs. So: more, please.
Stoller will write Get Him to the Greek in addition to getting back in the director's chair. He has some other projects in the works, including Five Year Engagement, which he will direct and co-write with Jason Segel. He's also working with Segel on his planned Muppet movie. And he co-wrote the screenplay for Jim Carrey's Yes Man, due in December. Busy guy; lucky, too.
