A couple of years ago (or whenever), when we found out that Heath was preparing to direct a film version of The Queen's Gambit by Walter Tevis, I set up an automatic Google search for that title, to keep watch of any developments. Turning that book into a film was an excellent, insightful choice for him.
The results of the search still trickle in, now and then, but Heath hasn't been associated with them anymore. I still can't seem to be ready to turn off that search. It was the Heath project I was most excited about.
