In "The One About Trust", Margaret Faye incorrectly guesses Connie's name as "Katie".
In "The Malted Milkball Falcon", after an all night rocking chair competition, Emily Jones says "The sunrise... It's so pretty..."
Adored by the Network: While the Animated Adaptation is syndicated to many stations, FamilyNet seems to keep it on their Saturday morning roster. When there is only one toon on the line-up, odds are it's usually this.
FamilyNet dropped the show in the 2011-2012 season and replaced it (in the 'sole animated show' placement) with Monsters and Pirates.
The Cast Showoff: Some recent Odyssey episodes feature Eugene Meltsner playing the ukelele (based on voice actor Will Ryan's skill at playing the instrument). Also, Aria Curzon, voice of Mandy Straussberg showed off her singing talents on a few episodes.
The Danza: Early Odyssey character Ann Jacobs was voiced by Ann Ault.
Dawson Casting: A number of child characters are voiced by adults (as opposed to child actors aging faster than their characters):
Missing Episode: A few early shows starring a bumbling police officer (named Officer Harley) were pulled and re-recorded when parents complained that he gave children the wrong impression of authority figures. Officer Harley's only appearance now is at the end of the episode where the Barclays get robbed and the Flashback about how Whit acquired Whit's End.
Old Shame: Katie Leigh (voice actress for Connie) played a major character from the Dungeons & Dragonsanimated series, a fact which got a bit awkward after AIO did an episode condemning the role-playing game, "Castles and Cauldrons". Of course, considering how much fantasy voice-acting there is to do, most of the cast probably view that episode as Old Shame themselves. In any case, when the D&D came out on DVD in 2006, Leigh was the only member of the cast to reprise her role as Sheila for (appropriately enough) the radio play of "Requiem". In earlier interviews she said she'd be quite happy to do the role again.
Even before the animated series ended production, it was pretty clear that the writers were somewhat embarrassed by it and its noticeable difference in tone and writing. "A Day In The Life" was a partly a satirization of the changes in the animated series, wherein a Hollywood studio comes to make a movie about Odyssey and keeps making ridiculously over-the-top changes to make the movie more interesting until you can barely tell the movie's about Odyssey at all. "I Slap Floor" even contained a Discontinuity Nod where (a slightly unhinged) Whit draws up plans for the Strata-Flier (Whit's standard mode of transportation in the animated series) and raves about the adventures they can take in it and the people they can save. Everyone else in the room thinks Whit's being ridiculous.
Tom Riley: "Maybe you should lie down, Whit."
Whit: "Well, you'll be sorry the next time someone falls off a clock tower!"note This was something that actually happened in the animated series to Dylan.
Within the radio show itself, we have the episodes that featured the klutzy police officer David Harley, who was quickly dropped when parents complained that he was giving kids a bad idea about police officers, and the episodes either went missing or were either rewritten or rerecorded without Harley in them. In one case the early episode "Lights Out At Whit's End" was pulled, not just because of Harley, but because the episode was just too weird, featuring little in the way of aesops (aside from a vague "it's good to spend time with your friends" moral) and ending with a random free-style rapping session that even Tom Riley and Whit take part in! The episode isn't even included in the "Lost Episodes" album.
The Other Darrin: Whit's voice actor was replaced after his original one died. And then again after he died too.
When Katrina's bus came in, her actress had changed as well. She's even quieter now.
Walker Edminston passed away before he could finish recording Bart's lines in the episode "Suspicious Finds" (wherein Bart was a major character). Bart's lines were rerecorded with another actor.
Marvin Washington went through three different voices during his run on the show.
All three of the Parker children have had their voices replaced once. Special notice goes to Matthew Parker; who has been voiced by three actorsnote original voice actor Zach Callison gave way to Gunnar Sizemore before the 2014 season; with Sizemore voicing Matthew Parker for just over a year before giving way to current (as of 2016) Justin Felbinger in a space of roughly 2 years.
Averted narrowly with Eugene; the writers initially thought about having Steve Bridges stand in for Will Ryan to record the message on Whit's answering machine at the end of "Exit", but decided against it and simply spliced together clips from old episodes (in similar fashion to the messages Whit left on the Whit's End answering machine during the Blackgaard arc or an earlier Novacom episode for which neither Will Ryan nor Pamela Hayden could record Eugene or Katrina).
Vance King's voice in his debut was provided by JasonEarles, where all other appearances have sporadically voiced by either Earles or Jason Marsden.
Recycled Script: After the episodes starring the bumbling police officer Harley were pulled (parents objected because they gave children the wrong impression of authority figures), the episodes were rewritten to feature a bumbling private investigator instead.
Romance on the Set: During the early years, the character of Lucy Cunningham-Schultz was voiced by Genni Mullen, while the role of Jack Davis was played by Donald Long. Around the time their characters were phased out, Mullen and Davis ended up marrying, and when their characters appeared again in a 2008 episode shortly before the most recent ReTool, Lucy and Jack got engaged.
Earl Boen as Edwin Blackgaard and Dr. Regis Blackgaard (although they only ever interacted with each other in one episode).
Steve Burns as Rodney Rathbone and Robert Mitchell.
Corey Burton and Will Ryan have Loads and Loads of Roles, regularly playing bit characters as well as multiple recurring characters (Walter Shakespeare and Cryin' Bryan Dern for Burton, Harlow Doyle and Eugene Meltsner for Ryan).
Technology Marches On: Hoo yeah. The show has utilized technology in every era, from dazzling arcade machines to pagers and beepers to top-of-the-line "laptop computers" and "cellular phones" to a brand-new computer having "one of those high-speed lines" to people sending "text messages" to AppleBerry smartphones. Nothing makes you feel old like having a fan question why Connie didn't just call or text Eugene or Bernard about Whit leaving on the cell phones they wouldn't have had yet in the early 1990s.
What Could Have Been: A lot relating to the "Darkness Before Dawn" Story Arc, as detailed in the various guide books released over the years. Among other things, the arc was meant to be the Grand Finale of the series, and would have featured some plot elements involving Dr. Regis Blackgaard possibly making a Heel–Face Turn, Richard Maxwell dying, and Whit's End burning to the ground. When the writers realized that they had introduced other questions along with the ones they had intended to wrap up, however,note for example, how Katrina would react to Eugene's new-found faith or whether or not Whit would ever return to Odyssey they felt that they needed to address these, and the series continues to this day.
In the Novacom saga, the writers wanted to bring back Richard Maxwell to be the man behind AREM (a phonetic spelling of the initials "R.M."), but Maxwell's voice actor Nathan Carlson was unavailable, so Robert Mitchell was created for the role instead.
