Update: 10 November 2006:
A November 10 article in the Scottish
Daily Record
mentions that the script (now in the hands of Universal Pictures)
is being read
by Johnny Depp. The book's author, Graham Taylor, again mentions
that
Sean "has been approached" to play Jacob Crane.
This will remain a rumour unless / until
a press release or official sources
indicate Sean has actually been cast
as Jacob Crane.
