THE ANSWER MAN: In the course of knocking the new movie Saved!, I wrote, "The movie offers the liberal Christian theme that Jesus accepts everybody, but the credits include a nod to George Smith's defense of atheism. What's up with that?" The director (or someone posing as the director) e-mails me an answer: Smith's book appeared in one scene, and "a condition for using that book was to have a thank you in the end credits." Now that I've wracked my brain a bit, I do seem to recall that scene, though my memory may be playing tricks on me.
Curiously, Smith himself tells me he was unaware of this agreement, so presumably the party who insisted on the condition was his publisher. It seems odd that you'd have to get permission to include a shot of a book in your movie, but intellectual property law can be an ugly thing.
