!Film
* ActorAllusion: Peter Boyle as a TaxiDriver.
* CoveredUp: The theme song "Original Sin" was originally the title track for a Pandora's Box album written and produced by Music/JimSteinman and was later more famously covered by his frequent collaborator Music/MeatLoaf (with some lyrical alterations: only the movie version features lines about "who knows what evil lurks in the hearts of men").
* FakeAmerican: TimCurry as Farley Claymore.
* HeyItsThatGuy:
** [[Series/ThirtyRock Alec Baldwin]]. [[Film/TheLordOfTheRings Ian McKellen]]. [[Film/TheRockyHorrorPictureShow Tim]] [[Theatre/{{Oscar}} Curry]]. Need I say more?
** Yes, actually. Lamont's driver is [[EverybodyLovesRaymond Raymond's dad]]. The museum security guard is [[Series/StarTrekVoyager Neelix]].
** Al Leong (Film/DieHard[=/=]Film/LethalWeapon[=/=]BillAndTedsExcellentAdventure) helps kidnap ''[[WesternAnimation/KungFuPanda Po's dad]]''.
** The hypnotized taxi driver is [[Film/BillyMadison Carl.]]
** Dr. Tam is [[WesternAnimation/JackieChanAdventures Uncle]]. He was also Kenji, the man who designed [[WhereTheToysComeFrom Peepers and Zoom]].
** Margo Lane will later be known as Mary Kay [=LeTourneau=], at least if a LifetimeMovieOfTheWeek is anything to go by.
** "[[Series/{{Alf}} Hey, Willie]]! Why are you working at a museum?"
** Speaking of aliens on Earth, Lamont's uncle once had [[Series/MorkAndMindy Mork from Ork]] as his fat-er, I mean mot-um, as his parent.
* HeyItsThatVoice: Creator/FrankWelker as the Phurba.
* MoneyDearBoy: This was one of the movies Sir Ian [=McKellen=] starred in to fund his film adaptation of ''Theatre/RichardIII''.
* PlayingAgainstType: Tim Curry, the mighty [[Film/{{Legend}} Lord of Darkness]] and [[Film/TheRockyHorrorPictureShow charismatic Sweet Transvestite]] playing an oily, sycophantic Gríma Wormtongue character.
* PropRecycling: The Phurba is the same knife from ''Film/TheGoldenChild''. Replicas of the Phurba have been made as tie-ins to ''The Shadow.''
* WhatCouldHaveBeen:
** The shooting script had a longer chase scene in the HallOfMirrors, including flashbacks and banter. However, an earthquake destroyed some of the mirrors, making the full scene too expensive.
** Creator/SamRaimi wanted to follow up ''Film/EvilDead2'' with this but was unable to get the rights. Instead, he directed ''Film/{{Darkman}}'', using some of the ideas he had for his version of the story.

!Pinball
* TheOtherDarrin: Tim Kitzrow provides the voice for Lamont Cranston/The Shadow, though Baldwin's speech from the film itself appears as well.
! Pulps and Radio
* ActorAllusion: Possibly. In his later years, Orson Welles's outfit of choice when appearing in public was loose-fitting black, oftentimes with a cloak and matching fedora. No red scarf, though. In ''Film/TheThirdMan'' he wore a black coat and fedora like The Shadow.
** Amusingly, The Shadow as depicted on radio never wore a costume.
*** [[ComicallyMissingThePoint He was naked all the time?]]
* {{Defictionalization}}: The Shadow actually began as just the host character of a radio adaptation of the ''Detective Story'' magazine. When people kept asking for his non-existent magazine, Street and Smith ended up creating one with WalterGibson as the main writer.
* EnforcedMethodActing: OrsonWelles never once read the scripts before recording, so whenever Lamont sounds surprised you can be sure it's genuine.
* ExecutiveMeddling: Worried that the character was getting too powerful and too difficult to challenge, the writers were ordered to scale back the character's powers to just invisibility (and that they add in weaknesses to even that), and restricting Cranston to using invisibility only twice an episode (at the halfway mark and right at the end).
* HeyItsThatVoice: The original Lamont Cranston was none other than OrsonWelles.
** The original Margo Lane was played by Agnes Moorhead, who later played Endora on Series/{{Bewitched}}.
** The original voice actor for cab driver Moe "Shrevie" Shrevnitz was Alan Reed, otherwise known as the voice of [[TheFlintstones Fred Flintstone]]. Reed also often played other LargeHam characters, especially villains.
** After Welles left the show, Bill Johnstone took over the role. While not very well-known today, he was a prolific radio actor and showed up in a lot of shows of the time, most regularly as Dr. Franz, sidekick and mentor to the radio BlueBeetle, and he even had a major role in the very first Orson Welles episode of the Shadow (as a man falsely accused of murder) and turned up in other roles on the show even after he left the lead role.
** Likewise, Shrevie was played by several voice actors after Reed, including [[SantaClausIsCominToTown The Winter Warlock]] / [[WesternAnimation/TheLastUnicorn Captain Cully]], Keenan Wynn.
* TheOtherDarrin: The radio Shadow was played by several different actors. Same with the radio Margo.
