!!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: Creator/TimCurry as Farley Claymore.
* 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 1985}} 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.''
* TheMerch: Like ''Batman'' before it, ''The Shadow'' had a Kenner toyline. Unique among the figurines were "Electronic Bulletproof Shadow," which featured the Shadow's iconic laugh, and Dr. Mocquino, the Voodoo Master. Yes, that's right: ''[[ShownTheirWork Kenner resurrected an almost-unknown character from the pulps for their toyline.]]''
* 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).
* FollowTheLeader:
** A radio series called ''The Avenger'' was an obvious attempt to copy the success of the Shadow series, right down to the hero, Jim Brandon, being a mind-reader with the power to turn invisible, though he used electronic gadgets and chemicals rather than the Shadow's hypnotism and telepathy.
** The Franchise/{{Batman}} began as basically the Shadow in a bat suit before developing his own style; in particular, his 1939 debut "The Case of the Chemical Syndicate" bears a striking resemblance to a 1936 story from ''The Shadow'' magazine called "Partners of Peril".
** WesternAnimation/DarkwingDuck is a more recent example of a homage (bordering on parody).
* TheOtherDarrin: The radio Shadow was played by several different actors. Same with the radio Margo.
