Creator's Favorite: Rolf is Danny Antonucci's favorite character. Also an Author Avatar, since Rolf's backstory and different traditions are loosely based on Antonucci himself and his relatives (Antonucci is part of an Italian immigrant family).
Averted with all the characters except for Kevin, who's voiced by Kathleen Barr (who also voices Marie Kanker)—ironic, given that he's usually the toughest and most masculine out of all the male characters on the show.
Jonny is voiced by a female in the Mexican Spanish dub.
Jonny is voiced by a female in the Italian dub as well (and for some reason he's called "Jonnino").
In Sweden, Rolf is a fairly common name, so in the dub his name was changed to "Reinar" in order to sound more foreign-ish. Nazz's name was changed to Tess, presumably to make it easier to come off the tongue.
In Brazil, the name and nickname of the three characters were changed in accordance with the portuguese counterpart to "Edward." Ed was renamed "Du," Edd/Double-D was renamed "Dudu," and Eddy was renamed "Edu." It should be noted this resulted in Aerith and Bob, since every other character retained their original name.
Came dangerously close before actual production started. Danny Antonucci first pitched the show to Nickelodeon, but their first demand was that he relinquish all creative control.
The show's transition to digital ink and paint during the fifth season came at the behest of Danny Antonucci, who wanted to keep using cels to maintain the "old school" cartoon look. By that point, cels simply weren't cost-effective.
I Knew It: Some fans accurately guessed that Eddy's Brother would both appear in the movie and be the antagonist.
Keep Circulating the Tapes: "May I Have This Ed?" and "Look Before You Ed", the only episodes made for the show's sixth season before Danny Antonucci decided to scrap the remainder of it for the movie, aren't available on iTunes or any other digital service.
Missing Episode: Three. "Special Ed", which was finished but never aired due to (depending on who you ask) being either too surreal or "too real" for television. Not much else is known about it other than the fact that it might of been A Day in the Limelight for Ed, and may have even been an explanation of why Ed is the way he is, hence the "too real" explanation. The other two, "Luck Be an Ed Tonight" and "A Room and an Ed" may have never even left the planning stages.
No Export for You: Surprisingly, this Canadian series didn't air in Canada during its production and the creators had no idea what the final product looked like until long after it had aired in America.
The Red Stapler: Some fans developed a taste for Jawbreakers after seeing the candy act as a Macguffin on the show. Ironically, Danny Antonucci hates Jawbreakers and only used them for their comical size.
Nazz and May, Kevin and Marie, Sarah and Lee, respectively.
Ed and Eddy in the Swedish dub. Then it's talking to herself with the case of Kevin, Nazz and Lee in the same dub.
Throw It In: Averted. According to Matt Hill (Ed's voice actor), Antonucci was very strict on not having the actors ad-libbing any lines during recording, and would often demand well over fifty takes before he got exactly the inflection he wanted. Ed's random comments? All in the original script.
Unintentional Period Piece: Zig-zagged. While it's obvious that the show had elements that either were no longer seen in society (or were seen in a considerably lessened occurrence) or some viewers had never heard of, such as records, VCRs, the lack of any video game consoles, children spending most of their time outside and even Patric Caird's brilliant score for the show has a 50s/60s-ish vibe to it, the actual time frame of the show was intentionally left ambiguous. This way, viewers of all generations can enjoy it without being alienated by any overt and outdated references they may not get.
Urban Legend of Zelda: In 2001, a rumor about an Missing Episode known only as "The Scarecrow Boy Episode" surfaced. The story is that Sarah puts on a play - her own version of The Wizard of Oz - casting herself as Dorothy, Jimmy as the Tin Man, Eddy as the Cowardly Lion (apparently he was also tied to a chair the whole time because he kept trying to walk out on Sarah), Ed as the Scarecrow, and Double D as the director. Sarah became outraged with Ed continuously blowing his lines, and ended up kicking and locking him out of the house (while still in costume); when Kevin and other kids in the cul-de-sac see Ed roaming around, they keep calling him "Scarecrow Boy", which somehow causes Ed to grow stiffer and stiffer each time he heard the name. Eventually, the episode ends with Plank nestled into the ground, and Ed standing on top with his arms straight out, as if he has become a real scarecrow. There is absolutely no evidence whatsoever that remotely proves such an episode exists, though many fans swear to have seen it, and that it only aired once.
A comment by one of the show's storyboarders says there was an unused campfire scene in The Movie that would have divulged on the characters' Hidden Depths.
An episode called "Special Ed" was slated to air, but was scrapped for being "too real." No one knows what Antonucci means by that, but that won't stop fans from guessing. Rumors state it was going to be A Day in the Limelight for Ed. note Although "special ed" is short for "special education" which is, not exclusive to, but most commonly associated with kids who suffer mental retardation. For those curious, those with with focus or emotional issues — such as attention deficit disorder or Aspergers' syndrome — can also end up in special education. The episode was however before season 5 so it's unknown if the "it's about Ed being in special education" concept is accurate or if they just used a Punny Name for the title.
There are four other unmade episodes that are known: 'A Room and a Ed' in which Sarah and Jimmy evict Ed out while Ed and Sarah's parents are away so Sarah can have the house to herself, causing Eddy to swing into action, completely fed up with Sarah's brattiness. 'Luck be an Ed Tonight' in which Ed's horoscope tells him he'll have a lucky day, which leads Eddy to milk it for all it's worth. 'The Amazing Ed' a talent show episode, little is known beyond that. And an unnamed episode in which Eddy attempts to start his own religion, canned by Cartoon Network because they knew it would have sparked a huge controversy.
It's hard to believe, but this show was originally pitched to Nickelodeon as a Nicktoon. While Nickelodeon has a lot of radar-dodging shows, they don't go as far with it as Cartoon Network does (possibly because they don't want another The Ren & Stimpy Show on their hands). Even when pitching it, Antonucci knew that if Nickelodeon accepted the show, a lot would have to be changed for content and was proven right when their first demand was complete creative control.
Write Who You Know: All the characters are based on either facets of creator Danny Antonucci's personality, family members, or people he knew growing up. The Eds were all aspects of his personalitynote Edward being his middle name, Jimmy was based on a cousin, Jonny was based on a loner friend who spent time with a blanket, Rolf was based on his experiences as an immigrant, and the Kankers were based on a group of girls who harassed him in 8th grade. He probably (hopefully) didn't know anyone exactly like Eddy's Brother.
