Interesting that it says "based on a story by Dylan Thomas." In fact, Thomas wrote it as a teleplay. Maybe somebody else took credit for the script. Or, more likely, modified it to meet current Hollywood standards for gore. But really, Twiggy???

Of course, on that same horror movie website is:

Visiting Hours (1982)
In this hospital, your next visit may be your last. A female news commentator is stalked by a psychotic killer. When she goes into the hospital--look out! Lee Grant, William Shatner. 105 min.

Don't tell Little Hawk. (Wait, what am I saying? He probably owns three copies.)

Aloha,
