the giant spider invasion (1975)

aka Invasion of the Giant Spiders.
"You ever see the movie Jaws? It makes that shark look like a goldfish!"
When a black hole opens and allows some giant spiders out, two NASA scientists, Dr Jenny Langer (Barbara Hale) and Dr Vance (Steve Brodie), have to battle to save the world.
Predictable talkie that takes too long to get to the point!
