Yes - it was a fascinating story.
But I do wonder as to whether, following all this effort in disputes and court cases, Charteris thought it was worth it bearing in mind the way in which moving image portrayals of his character steadily got worse and worse through the years, culminating with a couple of French films (at least one of which I can attest is truly dreadful) and the Kilmer abomination.
Indeed, I think the nine b/ws are the best representation of the Saint to date. Moore's series benefitted from being direct adaptations, but then the Dutton and Clarke efforts were complete travesties.
We will see what happens if, as and when the new TV pilot ever gets shown as to where portrayals could go next. But to my mind, I have never understood why directors wish to keep 'reimagining' this character when a true portrayal has yet to be successfully effected.
