I've seen four movies based on books in the past week and all made me think about the perils of adapting novels to the screen. I once heard Peter Hedges speak about the difference between plays, novels, and movies. His novel, What's Eating Gilbert Grape, was adapted into a fine movie by Lasse Hallström, and he described the experience as a master class in understanding the difference between print and film. He said that novels are about what people think and feel, plays are about what they say, and movies are about showing what the characters think and feel, most often without saying anything.
I did not think much of the book The Jane Austen Book Club. If any other author's name was in the title, it would not have been a best-seller. The movie version is far better, genuinely enjoyable. Feast of Love and O Jerusalem did not live up to their source material. The Dark is Rising, The book that inspired "The Seeker" was so diluted in the final script that it had the same relaitonship to the source material that a homeopathic remedy has to its active ingredient. And the result was less efficacious.
It is not just about the acting. "The Jane Austen Book Club" has first class actors who bring more subtlety and complexity and life to the characters than the author ever did, but "Feast of Love" has Morgan Freeman, Jane Alexander, and Greg Kinnear, who all do the best they can but never make the relationships on screen feel immediate or alive. It just has to do with showing, not telling, and "The Jane Austen Book Club" manages that act of alchemy where the others fail.
