(Although referring to the movie and not the book) I found John Grogan's recent blog entry regarding the movie Marley & Me, quite interesting:
John Grogan's Blog: "The movie is not quite my book and not quite our real lives, and I think moviegoers, at least those who have also read or will read my books, understand that. It's a fictionalized movie inspired by my book, not a documentary. The director and screenwriters took liberties, invented characters and scenes and fudged some facts to make the story work for screen. I'm fine with that, especially because I have my books as a public record of the real story."
He adds that movie director David Frankel did a wonderful job that "captures the emotional truths of my family's experience."
I agree, in a movie, we might come to expect that the events are "based on fact." I recently read an article on the movie "Twenty-one" and the far-from-fact portrayal of many of the details and people in that movie. In non-fiction books, however, I think the reader is expecting more than just the essence of the truth. It's not always easy to convey the facts in the most interesting fashion when you have to stick to the truth. More than once I've interviewed a narrator, hoping for a certain answer that would fit perfectly in the story I'm writing. And when the narrator's answer is not what I hope for, it's disappointing. The trick is to craft something interesting and exciting around that true answer. When we've succeeded at that, the outcome is an article we can feel confident is both factual and entertaining.
P.S. Speaking of Marley and Me, I also enjoyed reading that Cesar Milan from National Geographic Channel's The Dog Whisperer has been working with Grogan and his family, and their new labs Gracie and Woodson. Yay!
