Grayson was actually very unhappy with how her work was presented in End/Road. She did the movie for a specific scene and it wound up on the cutting room floor. She had also hoped that the movie would be a breakthrough role in terms of the image H'wood had of her from her role in Iguana; the movie was delayed for a year due to the director's obsessive re-cutting of the final print, and slapped with an X rating due to a couple of explicit scenes (including Harris Yulin's brief full frontal male nudity). As a result, the movie barely registered at the box office.
Grayson's total screen time lasts about four minutes. I happen to be very intrigued by her work in this, but it's really an item for Hall-o-holics only.
