!!!The series and first two movies (1965-68)

* CreatorsPest: Creator/GerryAnderson hated John Tracy due to his "all-American" quality, among numerous other reasons he has cited over the years, which is why John is so rarely seen in the series.
* {{Defictionalization}}: [[http://en.wikipedia.org/wiki/International_Rescue_Corps There's an actual International Rescue,]] which began operations in 1985 and named itself after the organization found in this series. That's about where it ends, though; there are (sadly) no Tracy boys and (even more sadly) no ''Thunderbird'' craft to be found. (This could also explain why IR is referred to all but once as "the ''Thunderbirds''" in the 2004 LiveActionAdaptation.)
* DemandOverload: When Creator/TheBBC began re-running ''Series/{{Thunderbirds}}'' in 1992 (after it had been off the air for several years) stores quickly sold out of Tracy Island toys. As a compromise, ''Series/BluePeter'' came up with a build-it-yourself version.
* EditedForSyndication:
** The infamous ''Turbocharged'' version of the series, as well as a prior attempt to air the show on Creator/FoxKids, were both this; see CutAndPasteTranslation.
** When the original series was rerun on the now-defunct American network [=TechTV=] (including its short-lived merger with Creator/{{G4}}), the network split the episodes into two half-hour segments, usually aired one right after the other, and included pop-up trivia facts throughout the episodes.
* ExecutiveMeddling:
** A positive example when Lew Grade ordered the series be made with hour-long episodes. This required the series to delve into more sophisticated plot and characters to make up for the time, which made the series a cult classic.
** Sadly, a negative example from Lew Grade, and an unintentional one at that: The show was axed from airwaves after Grade's rather unsuccessful trip to America, where all three major networks were bidding on the show. Thanks in part to Grade's playing each network off the other and trying to raise the price, when one network dropped out, [[FollowTheLeader the others followed suit]], and Grade felt that without American involvement the show was too expensive to produce.
** Further series were denied after TheMovie (actually ''two'' movies) bombed, although this still had [[Series/CaptainScarletAndTheMysterons some positive effects]].
** ITV holds the rights to the series and refused to return them to Gerry Anderson or allowing him to either remake or continue the series à la ''Captain Scarlet''. By 2011, this was resolved, allowing [[WesternAnimation/ThunderbirdsAreGo the new series]] to proceed.
* FakeAmerican: All voice actors (save Virgil's, who quit after season one) were either British, Australian or Canadian, while most of the main cast was (implied to be) American.
** The Tracys were going to be British but then it was settled that they would be primarily American was so that the series would fair well in the U.S. because at that time the U.S. wasn't that accepting of British T.V. Sadly, the series became obscure in the U.S. and to make matters worse, the most attention anything related to the name of "Thunderbirds" was the [[InNameOnly 2004 film]].
* KeepCirculatingTheTapes: Good luck watching ''Thunderbirds'' in its original uncut format. Six episodes were edited into a trio of [[CompilationMovie compilation films]] for American broadcast in the early 1980's. While the remaining episodes were later released with no major edits, the only way to see the outstanding six were to tape them during the 1990's reruns, or import copies from countries where the episodes were released unedited (such as Australia).
** After securing the rights to the series in 1999, Carlton hastily remastered and released ''Thunderbirds'' on DVD and VHS. Unfortunately, while the films were replaced with their original counterparts, every episode featured new (and sometimes incredibly loud) sound effects. In the case of ''"Trapped In The Sky"'' and ''"The Perils Of Penelope"'', both were given new title cards.
** Even the Blu Ray releases weren't immune to pruning. In a bizarre attempt to sell the series in widescreen, ITV cut off the top and bottom of the fullscreen prints.
* NamesTheSame: Tin Tin shares a name with [[Comicbook/TinTin a certain Belgian reporter,]] which is the [[ScrewedByTheLawyers chief reason]] her name was changed to Tanusha "Kayo" Kyrano in the remake.
* TheOtherDarrin: Virgil was voiced by David Holliday in Series 1 and Jeremy Wilkin afterwards.
* ScrewedByTheNetwork: According to ITC themselves, Fox Kids' hacking to bits of the show was the reason why it failed and was taken off the schedule after about a month. (Still didn't stop them from creating the ''Turbocharged'' version.)
* ScrewedByTheLawyers: [[http://www.imdb.com/title/tt0057790/alternateversions Apparently]], the reason why the Fox Kids and ''Turbocharged'' version were redubbed was because Music/MichaelJackson had the rights to the original music and vocal tracks, having purchased them in the mid 80s. (You might be wondering how ''that'' happened. When Jackson purchased the rights to Music/TheBeatles' catalog, it included the rest of ATV Music- ATV having been Lew Grade's Creator/{{ITV}} station in London and the Midlands. ATV and ITC were fused at the hip during the era, and hence presumably it came under ATV's music dept. which then got bought by Jackson.) However, it seems all that legal stuff got cleared up by the late 90s and all further releases have had the original music/voice tracks (though several sound effects are still dubbed over, but not in every episode).
* ShortLivedBigImpact: The series was cut short after just 32 episodes, yet it managed to retain a loyal fanbase to this very day, is still regarded as Gerry Andersons' best work, and still has other shows pay tribute to it.
* TalkingToYourself: David Graham voices Gordon, Brains, Parker and Kyrano.
* TechnologyMarchesOn: A given in the Gerry Anderson shows. You have space stations, hypersonic rocket planes, and a mobile computer the size of a grand piano!
* ThrowItIn: During filming for the episode "Trapped in the Sky", Elevator Car No. 3 went out of control. The production team decided to include this in the episode, adding a shot of it crashing into a nearby airliner.
* UnintentionalPeriodPiece: Given this was made in the '60s, this was going to be inevitable. Modern British viewers may be a little miffed at the main airport being called "London Airport", unaware that back in the day, this was actually the name for Heathrow Airport before Stansted and Gatwick acquired "London" status. There are also several references to Cape Kennedy.
* WhatCouldHaveBeen:
** Creator/GerryAnderson and later on, whoever happened to own the rights to the original series, had tried multiple times to get the series back on the air; some of the later Anderson-backed projects were rewritten to remove references to this show, but then got cancelled during production for one reason or another.
** John was originally conceived to be the pilot of Thunderbird 2.
* WorkingTitle: ''International Rescue''

!!!The 2004 movie

* ActorAllusion: Several shots of ''Thunderbird 3'' in action are blatant references to Bill Paxton's ''Film/Apollo13'', as admitted by Jonathan Frakes on the DVD commentary.
** A ''Director'' Allusion- when Alan goes to pilot ''Thunderbird 4'', he tells Fermat "You have the bridge" of ''Thunderbird 2''- that being a frequent line directed towards Commander Riker in ''Series/StarTrekTheNextGeneration''.
* BreakawayPopHit: Busted's "Thunderbirds Are Go", which got to Number 1 in the UK charts -- and won Record of the Year for 2004.
* [[BreatherEpisode Breather Project]]: Per Creator/JonathanFrakes on the DVDCommentary, the movie served as this for Creator/BenKingsley- who desired a lighter, less emotionally taxing project- and ''especially'' for Anthony Edwards, who ''needed'' a bright, optimistic project like this after so many seasons on ''Series/{{ER}}''.
* CreatorBacklash: The original series' creator Creator/GerryAnderson initially disliked the film, calling it the "biggest load of crap I've seen in my entire life". However, co-creator Sylvia Anderson had a more positive reaction.
* CreatorKiller:
** Screenwriter William Osborne's career has never recovered from being credited on this '''and''' ''Film/FatSlags'' in the same year.
** Creator/JonathanFrakes hasn't directed another feature film, and has since focused on acting and TV directing.
* CreatorPreferredAdaptation: Shockingly enough co-creator Sylvia Anderson loved the film.
** DisownedAdaptation: Gerry Anderson himself is on record as saying that ''Film/TeamAmericaWorldPolice'' -- a movie he didn't entirely approve of -- was closer in spirit to the original show.
* DeletedScene: Several of them- the known ones are as follows:
** An alternate opening with Alan riding a dirtbike
** A quick scene showing Virgil piloting Thunderbird 2 during the oil-rig rescue before handing it over to Jeff
** Jeff questioning whether or not putting his sons in constant danger is worth it
** [[FunWithAcronyms The acronym FAB being explained]]
** Jeff explaining why he left the Hood in the mine
** An alternate version of Thunderbird 2 landing in London
** FAB-1 being torpedoed by The Hood's submarine, leading to Penelope and Parker having to use a pedal-powered boat to reach the island
* MissingTrailerScene: A few alternate takes and deleted scenes were in the theatrical trailer.
* OrphanedReference: TheStinger is TheArtifact from a DeletedScene where FAB 1 got shot down by The Hood with his submarine.
* SoMyKidsCanWatch: According to Frakes, Creator/BenKingsley took the role partially on the urging of his kids.
* TroubledProduction: Had been in DevelopmentHell since the mid 90s. It was originally conceived as a CGI film, inspired by the success of ''WesternAnimation/ToyStory'' and then later as a vehicle for the Baldwin brothers (with Creator/SeanConnery as Jeff). Creator/GerryAnderson was brought on as a creative consultant but let go when Working Title felt that they had enough people on the creative team already. Eventually it entered production with a much younger target audience in mind. Three major script changes also happened during production; not helping was the film "falling through the cracks" when Seagram (the liquor company) acquired Creator/PolygramFilmedEntertainment (who had started the project during their ownership of the ITC library) and merged it with Creator/{{Universal}}. Creator/JonathanFrakes did manage to knock $3 million off the budget due to his fast shooting style, but that seems to open up another can of worms altogether; outside of the death of a rigger who fell while dismantling a set, and a few cast members getting heatstroke, the filming itself went smoothly.
* WhatCouldHaveBeen:
** In 1997 a totally different movie was in the works, with [[Film/BillAndTedsBogusJourney Peter Hewitt]] directing. The tentative cast was [[Film/ThatThingYouDo Johnathon Schaech and Tom Everett Scott]] as Scott and Virgil, Creator/MattDamon as Alan, [[Film/DiaryOfAWimpyKid Steve Zahn]] as Gordon, Creator/RowanAtkinson (!) as Brains, Creator/LivTyler as Tin-Tin, [[Film/TheEnglishPatient Kristin Scott Thomas]] as Lady Penelope, and [[Film/TheLostWorldJurassicPark Pete Postlethwaite]] as Parker; it's unknow who would've been Jeff, but rumor states that Creator/RobertRedford was being looked at. The plot would've revolved around IR being targeted by [[CorruptCorporateExecutive deranged Moonoleum Incorporated director Thaddeus Stone]], who had constructed an orbiting atmospheric extraction device that would transfer Earth's atmosphere to Stone's colony on the Moon, leaving the Earth barren and lifeless. In order to complete his plans, Stone needed to get his hands on Tracy Island's power core, the only generator powerful enough to fuel his extraction device. With assistance from The Hood, Stone learned the location of Tracy Island, kidnapped Alan and forced Jeff to hand over the power core, leading to a race against time to save the Earth- amongst the details were a new rendition of the Skythrust airliner (which would've crashed into Big Ben), a sports car named after the Fireflash and the dramatic self-destruction of Thunderbird 1 after a high speed night pursuit over Tokyo.
** Another draft was far closer to this movie, but was full of adult jokes, and instead of the Hood a man named Aristotle Spode would've been the main villain ([[EarlyDraftTieIn some press releases and info packs about the movie still had his name mentioned]]). This version would've been even ''worse'' than what we got, so be thankful.
** A late draft had another intro where Alan dreamt about flying Thunderbird 1, but the dream becomes a nightmare when he crashes into a mountain with a giant effigy of Fermatís face on it. Ummm...
** Creator/RosamundPike was a candidate for Lady Penelope, but ultimately the role went to Creator/SophiaMiles; Pike would eventually voice the character in the [[WesternAnimation/ThunderbirdsAreGo CGI reboot series]].
** You know that bit where Parker cheers that England's national football team have won, causing him to be distracted from flying ''FAB 1''? Well, he was originally supposed to cheer on a reported victory of Tottenham Hotspur- they chose that due to the clubís proximity to Wormwood Scrubs prison, Parkerís former "accommodation"- but ultimately it was changed to avoid alienating parts of the British audience (that was bound to happen anyway).
** The Tracys were supposed to wear color-coded ''baseball caps'' early on, and some were even made, but they didn't go over well in screen tests and were subsequently dropped.
** They had initially attempted to have Rolls-Royce build a new FAB-1, but BMW (RR Motor Car's owners) said no because they were busy with creating the then-new Rolls-Royce Phantom. Ford took the job instead.
** An idea for the climax was to have the Mole as piloted by The Hood sever one of the supports of the London Eye and one of its' passenger pods would fall in. However, the people who ran it said no, on account of it being a potential terrorist target, and hence was changed to the "[[TwentyMinutesIntoTheFuture Olympic Monorail]]".
*** Another one was that ''Thunderbird 2'' would have swept through other parts of London, including near the Houses of Parliament and also past the Mayorís building, blowing all of its windows out. This was also dropped for security reasons.
** There was talk about having Sylvia Anderson and Frakes as passengers on the monorail, but scheduling issues prevented Anderson's appearance; Frakes instead cameoed as a cop at the end.
