Fantasy movies that I recall as D&D-inspirational but weren't on the list:
  - Princess Bride
  - Willow
  - Dark Crystal
  - Never Ending Story
  - Clash of the Titans
Oh, and E.T., because I found the D&D references fascinating as a kid. 
Disappointing was The Dungeonmaster. I was hard to disappoint at age 12, but man was that movie disappointing.
