* AwardSnub: Creator/JessicaWalter had gotten a Golden Globe nomination for Best Actress, leading some observers to believe she had a shot at an Oscar nod, but the film ultimately got zero Oscar nominations.
%% * SugarWiki/AwesomeMusic:
%% ** Some cool jazz music is featured throughout the the film. Including, yes, Erroll Garner's "Misty".
%% ** There's even a scene that was actually shot at the 1970 Monterey Jazz Festival, with footage of a performance by Cannonball Adderley's band.
* GeniusBonus: Evelyn quotes Creator/EdgarAllanPoe's "Annabel Lee", which provides {{Foreshadowing}} for her ultimate fate, [[spoiler:falling to her death in the ocean]].
* SugarWiki/HeReallyCanAct:
** Creator/ClintEastwood, the paragon of masculinity, plays a vulnerable stalking victim and does it very well. This film also showed that he was a talented director.
** Younger viewers who know Creator/JessicaWalter from her comedic portrayal of Lucille Bluth in ''Series/ArrestedDevelopment'' may be surprised by her range in creating a truly scary character.
* {{Narm}}: Some of Evelyn's dialogue can be rather over-the-top and come out of place in a thriller ("She couldn't get laid in a lumber camp!").
* NarmCharm: As silly as Evelyn's unbalanced antics may be, Creator/JessicaWalter gives a genuinely chilling performance as her, conveying how they are the work of a dangerous person.
* OnceOriginalNowCommon: Thrillers about a StalkerWithACrush and films with a violent villain tormenting average folks are a dime a dozen these days, so modern viewers may have trouble appreciating how novel, innovative and chilling this film was in 1971. Even the twist of having the BigBad be a fairly attractive woman has turned into its own cliche.
