That is my main point there is not much to hang an IP on except a name. Even Transformers had a basic storyline. So basically you are making a generic fantasy themed probably kiddie friendly movie where the prime example of a successful fantasy tie in (GOT) is adult themed and has an existing story to adapt. Drizzt is totally a no go for a bigscreen adaption but you could blend genres like an Isle of Dread backdrop perhaps.
The real problem is the best possible D&D movie has already been made.
It's Time Bandits.
Now, think of the protagonists. Instead of little people, imagine them as 1st level adventurers, Evil as a 20th level Wizard, and all the shenanigans and creatures they faced (Giants, Minotaurs, Robbers, Gladiators, Wretched Demons, Space ships, Cowboys) were the same stuff you saw in a typical kitchen sink D&D game in the 80's.
It wasn't about generic LOTR fantasy. It was hilarious stuff like falling through dimensions and time while being chased by angry floating heads, giants casually walking up from the bottom of the sea and carrying your boat away on it's head, and evil wizards casually blowing their toadying minions to bits in between witty repartee. Don't mention the final battle with spaceships and gunslingers all shooting at a Wizard who'w basically casting a shitload of spells and owning them all.
All due respect to Joe, but I think to be anywhere remotely in the spirit of the game, the D&D movie has to be a gory black comedy, involving an Oceans 11 style heist inside a dungeon, with a bunch of bumbling murder hobos who only do good against their instincts. Unfortunately, I think the time for movies like that, especially in the fantasy genre, has passed.
