At the end of the English title sequence, when the letters "Inspector" come down over "Gadget" with the Inspector forming the "I", you may notice that "Inspector" is indented slightly, which seems odd - most titles are left-justified or centered. In the French version, the indentation is gone because of the extra letter in the different spelling - "Inspecteur".
In the opening credits, the scene of the gadgetmobile transforming is from either episode 1-3 "The Farm" or 1-6 "Health Spa".
In the end credits, the scene of Chief Quimby in the garbage can and Gadget falling backwards past a railing are from the episode 1-7 "The Boat". The scene of the seagull picking at Gadget in the ffwater is possibly from a deleted scene from this episode.
The urban legend that Dr. Claw and Chief Quimby are the same person comes from the closing credits, in which Dr. Claw's voice track accompanies a shot of Chief Quimby. In the very different original credits from "Gadget in Winterland" (the pilot), Gadget caught up to Dr. Claw only to reveal that his foe had once again escaped. The "I'll get you..." line made perfect sense in context, but led to some misunderstandings when the series' "standard" credits sequence was instituted.
The original pilot was previewed as a special on Saturday December 4, 1982 on all five Field Communications stations: WFLD-TV Chicago, KBHK-TV San Francisco, WKBD-TV Detroit, WLVI-TV Boston, and WKBS-TV Philadelphia. The reworked version was syndicated as the 65th and final episode of season 1.
Breakthrough Hit: DiC Entertainment's first animated seriesnote alongside The Littles created specifically for an international audiencenote Their first series was "Archibald le Magi-Chien", created specifically for France/Europe. Their nexttwo series were Japan/France co-productions.. and perhaps its most well-known.
Executive Meddling: In the pilot episode, "Winter Olympics", Inspector Gadget had a mustache. DiC Entertainment had to remove the mustache for the rest of the series after MGM threatened to sue them for Gadget looking too much like Inspector Clouseau. In later airings of the pilot, a scene was redubbed explaining that Gadget's mustache was fake (with Frank Welker voicing Gadget's line.)
Fake Brit: Gadget in the pilot. This was dubbed over with Don Adams' rendition in later airings.
Fandom Nod: The direct-to-video film "Inspector Gadget's Last Case" ended with Gadget mistaking Chief Quimby for a disguised Dr. Claw, a reference to many fans believing that Quimby and Claw were one and the same.
Keep Circulating the Tapes: the series got a few single episode VHS releases that are now out of print. It also got a few episodes released on 2 compilation DVDs which are also out of print. The first season WAS released in 2006 by Shout! Factory but it's, you guessed it: out of print, and quite pricy, most sets go for about $50 apiece. There was also a DVD from Cookie Jar Entertainment that has the first 10 episodes from season 2 but again like everything else, it too is out of print. The series was available on Netflix for a while but it was taken off. The first 65 episodes are available as the first 3 seasons on iTunes though. And the series is beyond easy to find on YouTube. Though finding the original Jesse White version of The Winter Olympics pilot will be quite a task as it's currently considered lost.
Currently averted now that the entire series has been released on DVD in October 2013 and the final season was released on iTunes. The entire series can also be seen on Hulu.
The first version of the pilot had Jesse White voicing Gadget, but is currently considered lost. Then he was voiced by Gary Owens in the second version. Finally, Don Adams played the role in the third and final version of the pilot.
Maurice LaMarche played Gadget in Gadget and the Gadgetinis and the animated direct-to-video films Inspector Gadget's Last Case and Inspector Gadget's Biggest Caper Ever. He also filled in for Don Adams on occasion in the original show's second season when Adams couldn't do certain lines just right, and provided Gadget's singing voice in the 1992 Christmas special.
In the first season, whenever Frank Welker wasn't available, Dr. Claw was voiced by Don Francks (Cree Summer's dad). In the second season, someone else took over voicing Dr. Claw, though Frank Welker still remained on board as Brain and various incidental voices.
Brian Drummond provided Dr. Claw's voice in Gadget and the Gadgetinis and the DTV movies Inspector Gadget's Last Case and Inspector Gadget's Biggest Caper Ever.
In the pilot, Penny was voiced by Mona Marshall. In the second season, Holly Berger took over the role from Cree Summer.
She was also played by Erica Horn in the 1992 Christmas special and by Tegan Moss in Gadget and the Gadgetinis and the DTV movies "Inspector Gadget's Last Case" and "Inspector Gadget's Biggest Caper Ever".
Lee Tockar provided Brain's vocal effects in his guest appearance on Gadget and the Gadgetinis as well as the two animated DTV films "Inspector Gadget's Last Case" and "Inspector Gadget's Biggest Caper Ever".
Dan Hennessey voiced the Chief in the first season. The second season had Maurice LaMarche take up the role. Prior to both of their performances, Chief Quimby was voiced by John Stephenson in the original pilot.
The show itself nearly didn't happen- DiC and TMS were planning another series based on Lupin III called Lupin VIII (centered around one of Lupin's descendants), but the Leblanc estate killed the show while it was in production. Since both firms had invested a ton of money in the project that wasn't gonna happen, they needed to recoup the costs quickly- and Inspector Gadget was born.
Repurposed Pop Song: Youngstown's "I'll Be Your Everything," which existed before the film but still used a sample of the theme song for it's hook. A newer version was recorded for the movie, with more uses of the sample and lyrics alluding to the plot, as well as some of the more suggestive lines removed.
Star-Derailing Role: This was one of several film choices in the late 1990s that led to a slump in Matthew Broderick's career as a leading man. He saved a little face a couple years later on Broadway with The Producers, but the musical's 2005 film adaptation re-derailed him.
Coleman also does this to a degree in The Beverly Hillbillies, where he plays Mr. Drysdale. In the film, unlike in the series, it's an employee of Drysdale who's scheming to exploit the Clampetts, and Drysdale actually reacts in horror when he learns that one of his own employees is attempting to embezzle his most recent (and fairly unusual) clients.
Prop Recycling: Par for the course in the sequel, but it is nice to see the control panel from Scolex's remote-control van serving as Claw's do-everything console.
The project originated in 1993 at Universal, with IvanReitman producing and Jeph Loeb and Matt Weisman as the writers. (One wonders how that version would've turned out.) But this was halted when Capital Cities/ABC, who owned DiC at the time, was bought by Disney.
The role of Gadget was originally written for Kevin Kline.
