Whatever boundaries separate fantasy novels from movies from video games from role-playing games are delightfully blurred in Dungeons & Dragons: Honor Among Thieves.
A bard (who doesn't really play much music in the movie), a barbarian, a somewhat hapless sorcerer, a shape-shifter, and (for a time) a paladin, are on a quest to retrieve a magical stone that will resurrect a lost loved one. In true D&D fashion, the only way to break into the magically sealed vault that holds the stone is to retrieve another lost artifact (a helmet), which is hard to get to and well guarded, but it can be used to ... well, you get the idea. The movie has all the classic tropes of a D&D game (specifically, a heist adventure), and all the free-reeling fun of a good RPG session.
There's complications, plot twists, pieces of luck (both good and bad), and, of course, lots of swords and sorcery. It's funny (but thankfully, unlike a lot of modern movies, the humor isn't entirely sardonic). It's fast-paced. It's got plenty of action. Blend that all together with just the right touch of character arcs, workmanlike acting (no one takes their role too seriously, and that really works in this movie) and you get something unique: an RPG movie that can hold together as a movie while still keeping the feel of an RPG game.
