I was and am a Dragonlance fan. I'll also be the first to admit that a Dragonlance movie would be billed by movie critics (and rightly so) as a "Lord of the Rings imitator." Its first trilogy, while vastly entertaining, borrows so heavily from the LOTR that it flabbergasted me, years later, when I became familiar with Tolkien's trilogy.

I'm sure there are other parallels, but I'm not a Tolkien buff.
It's not a play-by-play, certainly, but there are tons of parallels. Dragonlance was the nouveau 1980's role player's LOTR - it was the LOTR version that was approachable by those who considered Tolkien's prose "dense."
