I have a secret goal with my editor - he has asthma and uses his inhaler, and after I send him a new manuscript, I'll have his assistant phone me and tell me how many times he had to get his inhaler out while reading a draft. It's my secret laugh meter.
The strength of film is its accessibility and immediacy. But the strength of books is that freedom to really depict anything you want because people are going to be reading it in private. So, I'm always trying to write with the immediacy and the constant motion of film but I'm also trying to write with the complete freedom of subject matter that books have.
