I have a vague recollection of seeing Shatner in a slasher movie, set in a hospital, back in the early 1980s. It sucked ass.
Imagine slasher-movie music playing as he hams his way down a darkened hospital hallway.
IIRC, he gets gutted like a pig. But he was wearing his TMP-style hairpiece.
That was "Visiting Hours", from 1982.
