Phantasm
I haven’t watched this 1979 film by Don Coscarelli in a long time. It has a bizarre dreamlike quality to it, probably enhanced by the groan-inducing acting and limited budget, but the Tall Man character and the flying silver sphere are now classic icons of horror.
I happened to watch the extended version, which seems to indicate that they originally removed some scenes where the older brother gets his younger underaged brother drunk and they “rampage” through an ice cream store!
