The Astral Factor

1978 ·1h 34m · ★ 4.1 (17)

Demonstrating that a little knowledge is a dangerous thing, a convicted strangler studies the paranormal and finds a way to render himself invisible. Once he escapes, he sets out to find and eliminate five women who remind him of the mother he murdered. A police lieutenant sets out to safeguard them and bring the invisible killer to justice.

Why it matters

A low-budget blend of paranormal thriller and slasher that rides its wild premise with unpolished charm and 70s grindhouse grit.

  • Early example of invisibility used as a stalking method, predating more polished genre entries.
  • Uneven acting and rough pacing can trip up casual viewers but add to its cult midnight movie appeal.
  • Practical effects on a shoestring budget give the killer’s invisibility an eerie, uncanny quality.
  • For fans of obscure 70s horror digging into regional indies where atmosphere and concept outrun resources.
