If you loved Audrey Rose, try The Body Snatcher
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 Robert Wise, and they both carry the dread, paranoid, slow burn mood tags, and they sit in Horror / Thriller territory. If that's the register that drew you to Audrey Rose, the second film will land in a comparable space — through a different lens.

What The Body Snatcher is
Foggy Edinburgh streets at dusk, horse hooves on cobblestone, a lantern sways. Gray, a cab driver, and Dr. MacFarlane are bound by a dark past. Robert Wise directs this 1940s horror classic.
