Doing synergies is one thing if you can get lucky and have no delays on either side. But I seriously doubt there will be anything in any of these adventures that the movie producers took or that Hasbro executives gave to make sure the D&D movie "matched" what the book has.
But that's much different than the people who are saying that there's some grand command from up on high at Hasbro telling the D&D designers to put X, Y, and Z in some book so that it can be used at some future point in a movie or tv show. Those kinds of comments are ridiculous.
Higher ups aren't needed, the folks behind the movie and likely future movies and tv shows have direct access to the game designers for questions and requests.
The movie directors asked Chris Perkins if FR had any Prisons with a specific set of parameters, there wasn't (at least as far as Chris Perkins knew), so he just made one in Icewind Dale and added it to the Adventure he was working on.
The Directors given got consulting credit for the book.
So it's not impossible that there was some kind of direct collabration I'm the upcoming adventure anthology between designers and directors etc...
