Do you remember a movie in the mid to late 60’s. A psycho kidnapped a girl, put a cage over her head with a starving rat, then pulled up the door and let the rat eat her face. Could have been only a lead up to more awful stuff but we left immediately.
It seems to me that it was not a well known movie like Ben or Willard.
“Horror Castle”(1963)
a woman captured by “The Punisher” has a cage placed over her head containing a starved rat – and it ravenously attacks her face.
