Origin In 1981,
Inspector Gadget creator
Andy Heyward left
Hanna-Barbera and traveled to
Paris to work with
DIC Audiovisuel after being proposed by the company to do so. As the company wanted entertainment for the
United States, Heyward combined ideas to originate Inspector Gadget. As Nelvana was no longer part of the production by season 2, the show was written by the DIC studio employees Eleanor Burian-Mohr, Mike O'Mahoney, Glen Egbert, and
Jack Hanrahan. as well as many episodes of the
Gadget Boy spinoff series, and Burian-Mohr additionally wrote dialogue for the educational show ''
Inspector Gadget's Field Trip''. Due to various recurring elements in the series, the basic plot of each episode was often the same. The geographic location of each episode differed, and it provided for some variety in the series. The series effectively provided viewers with both comedic and dramatic moments. Despite the censorship standards for American animated series in effect during the 1970s and 1980s, the series also included elements of
slapstick comedy. This was nearly forbidden at the time, but the censorship was less strict for a syndicated series.
Animation Alongside
The Care Bears Movie,
Inspector Gadget was
Nelvana's first foray into animation outsourcing. Most of episodes from the first season were animated in
Japan by
Tokyo Movie Shinsha, while a few episodes were animated in
Taiwan by
Cuckoo's Nest Studio, before being finished in post production by DiC and Nelvana. The pilot episode, "Winter Olympics" (a.k.a. "Gadget in Winterland"), was animated by TMS's subsidiary
Telecom Animation Film, who had a slightly higher budget than the rest of the episodes. The additional production facilities are
AIC,
Oh! Production.
Sunrise, and
Toei Animation who helped with the
cel painting process for the TMS-animated episodes. Nelvana was not involved with the show's 21-episode second season, for which pre-production was moved to DiC's own Los Angeles-based headquarters. The animation and post-production was generally done at K.K. DiC Asia (later Creativity & Development Asia), a Japanese animation house Jean Chalopin co-founded that DiC had some ownership in at the time.
Voice cast The role of Inspector Gadget went through two different voice actors before
Don Adams was cast. Adams was seen as perfect, because he had played the original
Maxwell Smart, the character that inspired Inspector Gadget. Dr. Claw, M.A.D. Cat, and Brain were voiced by Frank Welker. Francks remained with the show, and usually performed the voice of a henchman of Dr. Claw. Sometimes Francks would portray a secondary M.A.D. agent, with Welker (who usually performed the voices of the agents otherwise) as the other in episodes where Francks' voice was necessary. Penny was originally voiced by
Mona Marshall in the pilot and was subsequently portrayed by Don Francks' daughter,
Cree Summer, for the rest of the first season in her first voice acting role. Chief Quimby was voiced by
John Stephenson in the original pilot, and later by
Dan Hennessey for the remainder of the first season. After the pilot, all of the first-season episodes were voice-recorded in
Toronto at the Nelvana facilities. When production of
Inspector Gadget moved from
Nelvana in Toronto to DiC's headquarters in Los Angeles for the second season, all of the Canadian-based voice artists were replaced. Holly Berger replaced Cree Summer Francks as the voice of Penny while
Maurice LaMarche replaced Hennessey as the voice of Chief Quimby. Occasionally, LaMarche would fill in for Don Adams as Inspector Gadget whenever necessary. In 2025, LaMarche revealed that a young
Jim Carrey auditioned for the role of Corporal Capeman, ultimately getting beaten out by
Townsend Coleman. LaMarche believes that had he won the role, as well as the title role of Disney's
Bonkers, he probably would not have pursued a live action film career.
Music The theme music was inspired by
Edvard Grieg's movement "
In the Hall of the Mountain King" and was composed by
Shuki Levy. For many years, Levy had a partnership with his friend
Haim Saban, with Levy composing the music and Saban running the business. Their record company, Saban Records, (now
Saban Music Group) has provided music for many DiC cartoons and children's shows in the 1980s and 1990s, and is still running today. A soundtrack LP to accompany the series, named
Inspecteur Gadget: Bande Originale de la Serie TV, was released in France in 1983 by Saban Records.
Wagram Music made it available on online services such as Spotify and iTunes. An English-language soundtrack LP, entitled
Inspector Gadget – The Music, was released in Australia in 1986 through ABC Records. While many of its tracks overlapped with those of the French LP, five tracks were exclusive to the Australian LP. In her book
Robot Takeover: 100 Iconic Robots of Myth, Popular Culture & Real Life,
Scissor Sisters singer
Ana Matronic says she considers the theme music to be widely recognized around the world. The series was a "global hit" and its theme song became "iconic". She notes that copies of the original television soundtrack had become extremely rare by 2010. == Release ==
