HHB is one of my favorite Narnia books... it's the only one I couldn't put down. I actually got in trouble for staying up reading it past bedtime, the first time I read it. I think that of all of the Narnia books, it has the plot that would be most easily transferable into a good film. Unfortunately, that's not always the deciding factor in whether or not a book is made into a movie. I voted that it has just as much a right to be made into a film as the other books. I hope they do make it. It is important to the culture of Narnia and the other countries around it, as others here have pointed out.
