I really enjoyed this novel but it would be difficult to adapt since it is written from the perspective of the main character. Much of the drama is internal so the adapting writer may have to add some story elements
to make it more cinematic.

It's going to be interesting to see if they keep that internal dialogue in some way. It would be very nice if it was Bob style from Twin Peaks, where the other half is almost a physical person.

I don't know, if it's mainly internal it is going to be tough.

Did you like the book Doug?

If you want to give Jim Thompson's stuff a go, there were two omnibus collections published by Picador in the 90s that rounded up nine of his books, including this one. Could be hard to find now, though, but they'd still probably be cheaper than buying up the individual novels.

If this film goes ahead, it'll be the second film version of this particular book. I haven't read it in years, though, so can't recall an awful lot about it. Will be interested to re-read and then see the film.
