First of all, and to avoid all doubt, as at the moment of writing this there is no film biz going on with this book! This is just me having fun with a spurious dream casting for some of the characters for the book. Photos are all from imdb. Obviously this is also all just my picks as of today, and tomorrow they might all be different. If you have your own favourites feel free to disagree and propose your own if you like.
