First movie that comes to your mind that you associate with D&D
Ralph Bashki’s Hobbit is the movie that I associate with D&D the most. I thought that the Hobbit and D&D took place in the same universe as a kid. I was bothered that D&D spellcasting didn't work like Gandalf’s magic. Gandalf didn't have to memorize spells every day. This film was D&D in my mind; they fought goblins, there was magic, they fought a dragon, there were dark caverns to explore, there were riddles, etc. This was a quest undertaken by a bunch of bumbling adventurers. If you have never seen it, check it out. I think that Bashki did a much better job of capturing the spirit of the Hobbit that Peter Jackson is doing.
