I’d forgotten that before Clint’s Dave Garver slugs Jessica Walter’s Evelyn Draper and sends her plunging to a rocky seaside death, Walter gives Donna Mills’ Tobie Williams a severe haircut.

That has to be one of the ugliest and creepiest things a cinematic serial killer has ever done to a victim — “Before I stab you to death I’m going to chop half of your hair off.”

Clint was a young-looking 40 when he directed and starred; Walter was 29, Mills was 30 or 31, and John Larch, who played the amiable, well-dressed, Martin Balsam-like detective, was in his mid 50s.

Evelyn and Glenn Close’s Alex Forrest are birds of a feather. Okay, Evelyn is a bit more manic and unhinged. But they both slashed their wrists, and both threatened the hero’s significant domestic other during the climax.
