That Empire company looks like a dud to me - this would be my biggest concern. If someone or some business of credibility were behind the project then it might be exciting. It is a PR thing totally - they may have acquired the rights to a screenplay but in no way have they acquired the rights to Jim Henson. Isn't he and his image trademarked by now - sure he is. We'll all be keeping our eyes peeled though - like I said earlier, "You never know what will happen in Hollyweird~!" It's an old saying that we all use here because it rings so true.
