Split Personality?

[Morwen]

Back to Tolkien and the film rights- I do recall, but can't locate, the reminiscence of one friend just after JRRT sold the film rights- the old boy was positively gleeful, convinced that no film could ever be made at least in his lifetime, and grinning like the cat who ate the canary (or sold it some worthless swampland).

So he had his cake and ate it too. Is this a problem?

I don't see why it should be.

The purchaser bought the film rights of a published work. Presumably, someone would have read it before money changed hands. If that's the case, Tolkien could not misrepresent what was being sold nor could the purchaser claim to be mistaken about the nature of what was being purchased. Tolkien may have thought the film rights were worthless but he isn't guilty of duping anyone. If people know that you are selling swampland and they agree to purchase it anyway, then good luck to them.
