This was actually a hit movie
At first this movie would seem like a box office flop, costing 30 million or so and grossing only about 6 million.
However, like so many movies of the 80's and 90's this movie definitely found a new home, in video rentals.
I remember working at a video store in the 1990's and this was available. It rented almost every night. it was one of the few movies that even rented on weekdays outside of any nightly promotions.
As evidence to the movie's popularity, the old DVDs are available on Ebay and usually sell for a lot of money for a DVD.
