Take your pick from among the horror sections.
I recommend The Video Dead and Galaxy of Terror!
[Yes, I am somewhat sadistic when it comes to B movies.]
Oh what the heck!!!
Just rent SPINAL TAP....the greatest movie of all time.
My high school band was in a scene from “A boy and his dog” More of a sifi than horror but definitely a “B” film.
