Wasn't he in this movie, too?
There's a scene towards the end of the movie where Ida Lupino is in the kitchen and a rat breaks in the window and kills her. I could swear this is the same rat from the 1983 movie Nightmares. I realize it was 7 years later and I don't know how long rats live, but their resemblance, mannerisms and acting style were uncannily similar.
