The Late Shift 2 is on its way!
Bill Carter's book The War for Late Night: When Leno Went Early and Television Went Crazy is coming in the Fall and is ready for pre-order. This is more or less "The Late Shift II" but for someone reason it's not being called that.
Pre-order here.

But will it be a movie? That seems almost like a foregone conclusion to me. It makes a lot of sense, because there's been a lot more drama in the Leno/Conan fight, I think.
