I realize the copyright to Forgotten Realms is owned by WoTC and Hasbro. I not sure if Mr. Salvatore has any say in things involving his characters or not.
I believe that many fans of Mr. Salvatore, and perhaps Mr. Salvatore himself, would love to see a live action movie or CGI animation movie based on his characters.
Developing either of these into anything beyond a dream would involve a large amount of money.
In order to convince the copyright owners that such a venture would be worth their while in creating extra awareness of their brand as well as financially would the administrators be willing to run a poll on here and the other related websites asking if fans would be willing to donate to the making of a visual adaptation of the works? i.e. using something like Kickstarter.com
Maybe that would convince WoTC and Hasbro to make something.
Just an idea.
Thank you for taking the time to read this. Have a great week.
