Scifi movie about aliens with hypnotic abilities and a levitating creature that covered the victims head like a shroud and killed them.

I saw the movie on TV in the early 60’s.  It was black and white.  The villains were, I think, aliens who could hypnotize by removing their shades and looking you in the eye.  They had some type of creature that they could summon for the purpose of killing people.  The creature looked to me (as a pre-schooler) to resemble a black umbrella.  It could levitate (or fly) and would sneak up from behind, settling over the persons head and blood could be seen flowing from beneath it.  I don’t know if possibly I’m combining more than one movie but I seem to recall towards the end that people who were taken by the villains (aliens?) were at one point alive but caught up in some type of webbing almost like a spider web but I don’t recall any spiders.  Anyone know of this movie?

  1. I definitely think it was “Not of this Earth”, but not sure about the people in the webbing. That one sounds like “The Beast From Haunted Cave”(1959).

Got something to say?
