I'm sorely tempted to create a fantasy campaign based on several B-grade movies. Why? Because while these movies may not have been great, they can still provide good ideas for a campaign. The setting would be a fantasy version of the earth. I chose these movies because they can be used together without too many continuity problems. I'm including the IMDB links to those films.
You already know about Hawk the Slayer and Dragonslayer, so I'll skip the synopses of these films. These films allow for dragons, dwarves, elves, giants, and wizards.
Here are a couple of lesser-known films shown on the Sci Fi Channel. I'll include the plot summaries, since the IMDB links don't give much detail.
Dragon Dynasty: European merchants visit China and are pursued on their way home by a sorcerer who controls a pair of dragons. Swordplay and kung fu fighting abound. A tribe of unwashed barbarians can substitute for orcs.
Dragon Storm: Rival kings team up to fight alien dragons. The dragons came from the stars, hatched from meteors (okay, it's not logical, but this is fantasy after all). The rival kings are more like NPCs. The real heroes include a woodsman/archer, a spoiled princess, and a merchant from the east who is a skilled martial artist.
I thought about including Dragonheart, but the dragon's depiction conflicts with that of the other movies. Still, talking dragons aren't unheard of, so I may include it. Likewise, the elves depicted in Legend are different from the standard rpg elf, so I dropped that too. Again, I may use a few elements, like the unicorns, the goblins, and the demon.
Suggestions and comments are always welcome.
