In the scene where Dr Alex Delaware played by Ted Danson is seated beside the wheelchair bound Professor Van Der Graaf at Jedson College, played by Charles Lane: Lane suddenly stands up from his wheelchair and walks across the room without any difficulty. As Lane steps over Danson to retrieve a book, the open-mouthed, dumbstruck expression on Danson's face is priceless as he looks at Lane, then at the empty wheelchair in bewilderment. Danson is momentarily rattled, then raises his brow, regains his composure and plays along pretending he doesn't notice Lane's blooper. Danson manages to seamlessly complete the remainder of the scene as if nothing unusual has happened.
In this film, Ted Danson and Richard Masur play characters who work together to bust a ring of child molesters. Both had previously played child molesters themselves: Danson in "Something About Amelia" (1984) and Masur in "Fallen Angel" (1981).
