Dungeons and Dragons is an extremely popular tabletop roleplaying game, and a new live-action movie (also titled Dungeons & Dragons) based on the game was released in 2023. In the meantime, though, there are many films and shows out there for players of D&D that share the same basic structure as many fantasy campaigns.
This structure is a quest narrative, where an individual or party of characters journey to complete their goals, sometimes saving the world in the process. While shows like Stranger Things, Community, and The Big Bang Theory casually reference D&D, they don't exactly follow this format. However, there is no shortage of quest stories on both the big and small screen.
I added Wizards and Warriors just because of fond memories
