SUBJECT: Rescue of your ip from idiot film studio and production of better movies.
Buy back the rights. Take the loss. Then hire Joss Whedon and his capable people to build a new franchise around the name. Give him the budget needed to get it going. That is all.
D&D is not LoTR. I think Whedon would do a much better job. He did a decent Traveller movie, after all.
In particular, a successful D&D movie should be lowish budget, quick, efficient, witty, and have some PC mortality - with ideally replacement PCs joining in mid-movie.
