Q+A
There's a video on youtube of a recent q&a screening with quite a few of the actors from the movie. It was very funny and entertaining.
Some of the actors talked about the movie being a box office disappointment. One of them even blamed the writer's strike. Which was actually in 1988, not 1987.
The movie wasn't a blockbuster, but for the budget, it actually did pretty good business in '87.
