Brain Leeches, The (1977)

Invading aliens are taking over the brains of folks in a small town. The head leech is a wad of black tinfoil with a couple of white thumbtacks for eyes. Others are spidery, ant-like rubber things pulled along by strings! Stars Paul Jones, Marcia Scott and Ray Starr. Directed and produced by Fred Olen Ray (credited as Brian Wolfe).
