Keep Circulating the Tapes: The film fell out of print after it's initial VHS release; the DVD did so too after it's release, as did the double feature disc that paired it with April Fools' Day. The Lions Gate DVD (which contains the uncensored cut of the film) is thankfully still in print.
What Could Have Been: A sequel was proposed, but ultimately declined. A treatment and/or script was apparently done for it however. Going by information that's out about it, it would have taken place in an amusement park built where the original mine killing occurred. The cut gore footage from the original was to inserted into the sequel as flashback sequences.
