Reality Subtext: Peter Cushing plays Grimsdyke, a widower who attempts to contact his wife via Ouija board. Cushing's own wife had died shortly before he took the role, and he evidently insisted that he would be perfect for it. Ouch. And Grimsdyke's wife is named "Helen"— the name of Cushing's wife.
Recycled Set: The framing story was shot at Shepperton Studios, in the cave sets built for Tower of Evil (aka Horror on Snape Island) earlier the same year.
Dawson Casting: Brad Dourif played the younger brother of Bill Paxton in the episode "People Who Live in Brass Hearses". Dourif is five years older than Paxton.
Bill Paxton as Billy DeLuca in "People Who Live in Brass Hearses".
Aron Eisenberg as Aaron in "Undertaking Palor".
Edited for Syndication: You better believe it. FOX used to run repeats in their prime-time line-up during the mid-1990s (mostly on Saturday nights after the local news), and the series later turned up on basic cable channels, like the Sci-Fi Channel, AMC, and Chiller. The show on all the non-premium networks was edited for gore, sexual content, nudity, violence, explicit language, and, of course, making room for commercial breaks.
Market-Based Title: Known as Hollywood Nightmare in Japan most likely due to how obscure the American comics are overseas.
Larry Drake built a career on playing creepy, dangerous villains (and indeed, played themost creepy and dangerous villain in season 1's "...And All Through the House"), but in season 2's "The Secret" he plays the slightly creepy but very kindhearted butler who befriends the young main character and ultimately dies trying to protect him.
The dryly unflappable Ben Stein plays a short-tempered and verbally abusive mortuary owner in "Doctor of Horror".
Well-known horror actor Michael Berryman, recognized for playing mutants and monsters, plays Rupert Van Helsing (a Vampire Hunter) in "The Reluctant Vampire". The normally serious Berryman delivers a wonderful comic performance in that episode as well.
Sam Waterston appeared in the Season 5 episode "As Ye Sow," playing an unscrupulous private eye who offered to (and did) hire a hitman on behalf of his client. He would debut on Law & Order one year later in the role of Jack McCoy, a prosecutor with an unshakable drive to see justice done.
While it wasn't out of the blue for actors to take on directing episodes, like Arnold Schwarzenegger and Michael J. Fox, Tom Hanks takes the cake with his episode "None But the Lonely Heart" where not only does it feature him in one of his few horror roles with his small part as a Video Dating employee (Who suffers a brutal death), but it also has one of the series most detestable lead's and ending twists. Makes you wonder how'd things would go if he focused on directing horror more.
This rumor was debunked by A.l Katz and Gil Adler. According to them Dead Easy never went past pre-production due to Universal pulling the plug on it and forcing them to make Bordello of Blood.
Real-Life Relative: "Lower Berth" guest stars Jeff Yagher, who is the older brother of Kevin Yagher (who not only directed said episode, but was a key person behind the Crypt Keeper's effects).
Real life father and son Kirk Douglas and Eric Douglas played father and son in "Yellow".
Screwed by the Lawyers: Why the franchise has yet to re-emerge aside from the occasional new comic. Specifically, HBO has been incredibly stingy with exactly how much they own, particularly in regards to portraying the Cryptkeeper, and their meddling has put several attempts at a revival on the backburner.
Besides Demon Knight and Bordello of Blood, there were plans for two more movies. Dead Easy (a New Orleans zombie romp) which would possibly have opened the following Halloween that year, and Body Count (about a documentarian who discovers his uncle's dark secret).
Demon Knight was supposed to be the second film in the original proposed trilogy, but Universal Studios thought it should go first because it was "the most Tales-like" feature out of the three. Ironically, it ended up being the only one made.
Peter Jackson had his own pitch for a movie entry: The Frighteners. Producers deemed it as being strong enough to be released as a completely stand-alone movie.
During the show's run, "Two-Fisted Tales", another more action-based EC comics creation, was to be adapted as a television series and three episodes ("Yellow", "Showdown", and "King of the Road") were produced. However the series was soon scrapped and the episodes were added to seasons three and four of Crypt, and was later repackaged in select markets as a TV Movie (which aired in the US exactly once.)
Miguel Ferrer appears in prominent roles in "The Thing from the Grave" and "In the Groove", as well as having an uncredited minor role in "As Ye Sow."
Michael Ironside has roles in both "Come the Dawn" and "The Sacrifice."
Joey Pants appeared in both "Dig That Cat, He's Real Gone" and "Split Personality."
Larry Drake appeared in "...And All Through The House" and "The Secret."
Lance Henriksen appeared in both "Cutting Cards" and "Yellow."
Sherrie Rose first appeared in "On a Dead Man's Chest" and later in "Only Skin Deep". Given how she's under heavy makeup in the latter, you'd be forgiven for not recognizing her.
Character actor Marshall Bell first appears in season one's "...And All Through the House" and later in season five's "Forever Ambergris".
Character actor Roy Brocksmith appeared in a few episodes: He has a prominent role as the mad surgeon in "The Switch" and had minor roles in both "The Man Who Was Death" and "Cutting Cards" (interestingly enough, playing bartenders in both).
Dummied Out: A great number of the Crypt Keeper's voice clips in the Rom are unused in the finished game. The unofficial 4.00 revision restores a number of them.
In Memoriam: The end of the pinball game's credits reads "In Loving Memory of William Gaines", the publisher and co-editor of the original EC Comics.
, the unreleased film Dead Easy (retitled Fat Tuesday) was finished, but due to higher ups at Universal 
thinking the film wouldn't be commercially viable, a script that called for a large African-American cast ended up being produced with a cast entirely of white actors. Out of fear of Unfortunate Implications, producer Joel Silver is said to have stepped in and locked the finished film away, hoping nobody would see or hear about it.
