As much as I love citing favorite movies (and seeing others'), I think we may have stretched the parameters of what constitutes a D&D movie to the breaking point.
Many of the plot devices we associate with D&D actually existed long before the game. For example, the group of adventurers with specialized skills and abilities brought together to find a fantastic treasure goes all the way back to Jason and the Argonauts (the myth, not the movie).
I propose that to qualify as a D&D movie, a movie must include at least one example of each of the following:
- time spent in a dungeon, sewer, cave, burrow, castle, fortress, temple, palace, or lair
- actual magic (arcane or divine)
- a fantastic or mythological creature (one that does not and never did exist in the real world)
- treasure (physical objects of high intrinsic and/or plot-device value)
- a random encounter (one that has little or nothing to do with the main plot or quest)
- a trap or obstacle (whether mechanical, magical, or natural)
By these criteria, most of the RW period pieces have to go.
