I have not, but my interest in it has been rejuvenated since our discussion here.
The movie seems to be largely unavailable for purchase, although Amazon has a hit-tracking page set up here: http://www.amazon.com/Wicked-Dreams-Paula-Schultz/dp/B000GBORYS. If there is enough interest (and Web visits,) I believe Amazon may provide it for sale. Regardless, I still suggest visiting your local video rental or retail store and requesting it -- those folks likely have more available avenues than we do.
Apparently the movie was based upon a novel or vice versa. The book version is widely available at all of the usual outlets. If I should find it, I will post the details. Please do so if you find it first.
Good luck.
