I'm basing my "nope" off of what I've read on IMDBpro. They have projects in the treatment stage profiled, so it's pretty comprehensive. As for the book, if they are simply bidding for the rights at the moment, any project would probably be pretty far off. It'll have to be adapted. At this point, Keira's as likely to play the lead role in the screenplay I'm writing, as she is Diana.
"Purgatory's kind of like the in-betweeny one. You weren't really shit, but you weren't all that great either. Like Tottenham."
I'll try being nicer...if you'll try being smarter.
