Yes, but it's still not <i>fundamentally</i> wrong to do so. Very little is fundamentally anything in storytelling. In the end, the only thing that really matters is to tell a good story. Anything else is a secondary consideration. So if a storyteller choses to retell "Romeo & Juliet", he'd better be focusing on telling a story. If he focuses on fixing things he didn't like, or on showing off how good he is at updating things, or even on being faithful to the source, then the story will almost certainly fail.<br /><br />In general, it's a good guideline not to rip off somebody else's work. Reason being, the audience will notice, and it may put them off. If that happens, the story will fail, because telling a good story means keeping the audience on your side so they're willing to suspend disbelief.<br /><br />But there is indeed a long tradition of rewriting stories by known authors for which a so-called "definitive" version exists. Many are no longer copyrighted, or never were, having predated the concept of copyright. Did you know that "Hamlet" is a derivative work? And the story of "Troilus and Cressida" wasn't just Shakespeare extrapolating from Homer's "Iliad". It was really a dramatic adaptation of Geoffrey Chaucer's poem -- and Chaucer most certainly should qualify as a known, published author, even if you don't think Homer should count.<br /><br />BTW, regarding Arthur, many scholars believe that the first "real" version of Arthur's story was <i>Le Morte D'Arthur</i> and that prior to that, there never really was a story of Arthur at all -- just dissociated pieces which Geoffrey de Monmouth knit together into a new story. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
