Here I go with another activity from "gamers that did more than just game" category of 80's memories. The trailer for Krull is below:
Several of us went to the theatre and saw this film. There was no D&D movie at the time but this was a close approximation to the way many groups played the game [atleast for a short period of time]- as in, they did not strictly stick to fantasy but also threw in a little science fiction also. Not to mention that TSR mixed science fiction and fantasy with EXPEDITION TO THE BARRIER PEAKS. I admit that it is not a cinematic masterpiece BUT it is better than the official D&D movie that we got.
