Aintitcool.com says that the settlement was around $220 million divided (not evenly) between the Tolkien estate and Harper Collins.
To quote from ainitcools take on the settlement, “This was always going to be the end of this particular snag, it was more about finding that number that all parties could live with.”
Wow! I wouldn’t have guessed it would be that much! And in a world (heh, heh!) where Hollywood does everything it can to show that films _lose_ money, the trilogy itself must have made a staggering amount.
