Thanks for bringing this to our attention.
For fans of grim, dramatic, female/damsel-in-distress quicksand scenes, this was nice. Yes - the quicksand is below water level, but the female does walk across the quaking quicksand before entering the water. And the director took time to show quick shots under the water, with legs in the quicksand. Plus, there is a menacing man watching her sink to her doom at the castle.
Alas, I would have liked to see this last longer, but for a TV movie, it is impressive. For those who want to learn more about the film, here is the IMDB link:
