Would that book be Persian Fire? I'm attempting to read it at the moment. I can't believe the film will be any good though - the trailer makes it look absolutely rubbish, with lots of scenery chewing.
Saw The Good German at the weekend - not as bad as the reviews said it was! Gorgeous George was as good as ever, but Cate Blanchett's Marlene Dietrich impression was the unintentional comedy highlight. As usual with Sonderbergh, it looked very impressive.
