Plays are always more likely to have multiple productions than novels anyway, though. The Pride and Prejudice analogy is more useful, I guess - and possibly in a couple of hundred years there will have been as many film/TV versions of LOTR as there have now of P&P. The point is still that it would be (is) daft to insist that any one of those adaptations has changed how the book is to be seen forever after.
