Halperin, who inflicted The Note on the world before moving to Time, sold an option HBO Films to turn into a movie his forthcoming 2008 campaign book Game Change, even though that book is effectively an extended correction on his last book.
The studio, which does projects for both the eponymous premium cable channel and the big screen, has already hired a writer (Charles Leavitt) to do the screen adaptation.
Halperin will serve as a consultant to the movie, alongside John Heilemann, the New York magazine political writer he's been blessed to have as a co-author on the book. HBO will need all the help it can get: Like the book, the film Game Change will attempt to track three campaigns and five politicians
Usually a movie like this would take you behind the scenes of a campaign, but there's only so deep you can go when you're hopping between Bill Clinton, Hillary Clinton, Barack Obama, Sarah Palin and John McCain. (Sad Joe Biden will apparently be reduced to a bit part.) Maybe HBO is thinking miniseries.
In any case, it will be fun to watch the casting decisions unfold, and to relive the 2008 campaign through the eyes of a man who thought John McCain was on fire the week he said "the fundamentals of our economy are strong." Maybe we'll find out he was right after all.
