Not much is known about this, except that it is an unfinished film that was never released. I mean, a script was written, but it never got past the stage. It's a shame. The title does give you a clue, however.
"Legend of Snaildarter"? Maybe the crew were planning on making this Snaildarter character half fish, half otter... but gosh knows what.
So, that's the end of my review.
