Reason it caught my attention is that I read in the Blu Ray review that this movie does not have the original intermediary elements used anymore because the negative had deteriorated: http://www.blu-ray.com/movies/Journey-to-the-Center-of-the-Earth-Blu-ray/39539/#Review

Here’s the excerpt:

“When Journey came to the then technologically “amazing” laserdisc format around 1990, it was evidently discovered that the original negative had deteriorated to such a point that it couldn’t be used for what would have then been a state of the art transfer. Apparently at that time new intermediary elements were created which may still be in use today, according to information passed on to me from Twilight Time’s Nick Redman. The results, while not completely staggering, are very good and should please ardent videophiles who bring appropriate expectations.”

I think it’s fair to assume that this 16mm print, although it’s described as “faded pinkish”, would stilll have all the original elements. With a bit of effort to restore the colors, this could make for a cool preservation project, I think.

$275 is the “Buy Now” price. I don’t really have any money to spare for this, but maybe someone here is interested? I also posted this over at fanres.
