If you loved The Manitou, try Day of the Animals
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by William Girdler, and they both carry the 3am cult, dread mood tags, and they sit in Horror / Science Fiction territory. If that's the register that drew you to The Manitou, the second film will land in a comparable space — through a different lens.

What Day of the Animals is
Mountain peaks at dawn, a helicopter's rotor. Hikers trek through forest, unaware of danger. Typical 70s eco-horror fare.
