* AlternativeCharacterInterpretation:
** Was Laura a beautiful-but-naïve woman who had the bad luck to get involved with an obsessive [[TheSvengali Svengali]] like Waldo Lydecker? Or was she a ManipulativeBitch who had a habit of using men like Waldo for her own purposes?
** Mark [=McPherson=]: intrepid investigator or {{Necromantic}} StalkerWithACrush? And when Laura returns, is she just a figment of his imagination?
* AwesomeEgo: Waldo Lydecker.
* SugarWiki/AwesomeMusic: The song "Laura" written for the film by composer David Raskin with lyrics by Johnny Mercer. [[BreakawayPopHit It became a jazz standard]].
* HilariousInHindsight: Mark has a small handheld rectangular baseball/pinball game he plays from time to time. The way he holds it in some shots makes it look like he's using a smartphone, in 1944!
* ItWasHisSled: Even during the film's original release, few people went into the theater without already knowing that Laura wasn't really dead. It's a testament to the film that the scene where she returns is so well-shot that it still retains a sense of tension and drama, even though most modern viewers are aware of the twist.
