* ActingForTwo:
** Creator/NicholasLyndhurst as Rodney in the show itself, and as his biological father Freddie the Frog in ''Series/RockAndChips''.
** In the 1991 Christmas special "[[Recap/OnlyFoolsAndHorsesS7E08MiamiTwicePartTwoOhToBeInEngland Miami Twice, Part Two: Oh to Be in England]]", Creator/DavidJason also plays Del's doppelganger mafia boss Don Vincenzo Occhetti, a.k.a. "Vinny the Chain".
** Creator/TessaPeakeJones played Raquel, but in "Time on Our Hands" doubled up as the voice of Joan Trotter.
** Creator/PaulaWilcox as Marlene's sister, Pertunia, in ''Series/TheGreenGreenGrass'', and as Grandad's wife, Violet, in ''Series/RockAndChips''.
* ActorInspiredElement: Creator/DavidJason came up with Del's cheap gold jewellery and his camel coat. The inspiration was taken from a similar man he had known when working as an electrician.
* AdoredByTheNetwork:
** There will be at minimum one or two episodes a day on UK TV Gold/Gold. On the most extreme days? What seems like non stop episodes from about dawn to dusk, to the point you could probably use the channel as an alternative to the DVD box set.
** Surprisingly averted early on. When ''Only Fools and Horses'' first aired both John Sullivan and David Jason felt the show was decidedly unloved at the BBC due to it portraying a working-class family in a London tower block, and complained that it wasn't receiving the same publicity and support as other programmes. Jason noted that the only publicity material about the show at the BBC television centre was near a toilet on a floor that only a few executives had access to. It was only after it became a [[MoneyDearBoy guaranteed ratings winner and cash cow for the BBC that attitudes changed.]]
* AscendedFanon: The official title of the 2014 Sport Relief Special was actually... well, [[ExactlyWhatItSaysOnTheTin 2014 Sport Relief Special]]. The episode was unofficially referred to as "Beckham in Peckham" by most of the press, then the fans, and finally the BBC themselves in subsequent releases.
* CaliforniaDoubling: "[[Recap/OnlyFoolsAndHorsesS2E06ItNeverRains It Never Rains]]" sees the Trotters go on holiday to Spain. Naturally, it was filmed in Bournemouth.
* CastTheRunnerUp: Creator/JimBroadbent was John Sullivan's original choice for the role of Del. While Broadbent turned down the role, he did later make three guest appearances in the show as DCI Roy Slater. Had Broadbent been cast, not only would we have had a completely different Del Boy, but he has stated in interviews that he would only have made one or two series before moving on, and thus the show would never have become the major hit it did later. Creator/RogerLloydPack was also considered for Del Boy before being cast as Trigger.
* TheCharacterDiedWithHim:
** When Creator/LennardPearce died, they decided to kill off his character, Grandad (off-screen, of course). Thus the first episode made after Pearce's death begins with Granddad's funeral.
** The same happened with Uncle Albert after the death of Buster Merryfield. Although Albert died ''during'' the episode, with the first scene explaining that he hadn't joined them in the Caribbean because it had turned out the great sailor didn't have a passport.
** Averted when Creator/KennethMacDonald (Mike the landlord) died of cancer in 2001. Out of sensitivity to his family Mike was not killed off, so it was explained that he was in prison.
* CharacterOutlivesActor:
** After the death of Creator/KennethMacDonald, who portrayed Nag's Head landlord Mike, his character's absence was explained by him serving a prison sentence for embezzlement.
** Eva Mottley made her one and only appearance as Denzil's wife Corrine in "[[Recap/OnlyFoolsAndHorsesS3E07WhosAPrettyBoy Who's a Pretty Boy?]]" She commited suicide by overdose just over a year later and John Sullivan chose not to recast her. Denzil mentioned Corrine many times over the series, though, and the two apparently divorced at some point.
** [[AvertedTrope Averted]] with Grandad and Uncle Albert, who died in the series following the deaths of the actors who portrayed them.
* CompletelyDifferentTitle: In Croatia, the show was called ''Scams''.
* {{Corpsing}}: In "[[Recap/OnlyFoolsAndHorsesS6E08RodneyComeHome Rodney Come Home]]", Creator/DavidJason is clearly trying hard not to laugh as Albert unsuccessfully tries to look "shocked" at Rodney.
* CreatorsFavoriteEpisode:
** John Sullivan's favourite episode was the 1988 ChristmasSpecial "[[Recap/OnlyFoolsAndHorsesS5E09Dates Dates]]".
** Creator/DavidJason's favourite was "[[Recap/OnlyFoolsAndHorsesS7E08MiamiTwicePartTwoOhToBeInEngland Miami Twice, Part Two: Oh to Be in England]]", because he got the chance to play two different characters.
** Creator/RogerLloydPack and Paul Barber named the 1989 ChristmasSpecial "[[Recap/OnlyFoolsAndHorsesS6E07TheJollyBoysOuting The Jolly Boy's Outing]]" as their favourite.
** Creator/JohnChallis' favourite was "[[Recap/OnlyFoolsAndHorsesS7E01TheSkysTheLimit The Sky's the Limit]]".
* DawsonCasting:
** Del Boy is said to have been a teenager in The60s. Creator/DavidJason was born in 1940, making him roughly five to ten years older than the character.[[note]]The show was inconsistent about Del's date of birth with this getting earlier over time. Early in the show's run [[Recap/OnlyFoolsAndHorsesS2E03ALosingStreak A Losing Streak]] explained Del's father left on his 16th birthday, with [[Recap/OnlyFoolsAndHorsesS3E08ThickerThanWater Thicker than Water]] placing this in 1965 (suggesting a birth around 1949). [[Recap/OnlyFoolsAndHorsesS1E01BigBrother Big Brother]] (the first episode) also established there was a 13-year gap between Del and Rodney. Later in the show's run, however, [[Recap/OnlyFoolsAndHorsesS9E03SleeplessInPeckham Sleepless in Peckham]] mentioned that Del was 15 in July 1960 (suggesting a birth of 1945) while Rodney had not been born yet. The school reunion episode has a banner celebrating class 4C (from context, the fourth year of secondary school) of 1962, meaning Del, Trigger, Boycie, and Denzil would all have been born between 1 September 1946 and 31 August 1947. The prequel ''Series/RockAndChips'' similarly has Del as 15 in 1960, supporting a birth year around 1945, with Rodney not born until later that year. This suggests the age gap between the Trotters was at least 15 years.[[/note]]
** Although Cassandra was supposed to be five years younger than Rodney, in real life Creator/GwynethStrong is actually two years older than Creator/NicholasLyndhurst.
* DoublingForLondon: The outdoor scenes were filmed in Bristol as the producers could not afford the insurance to film in Peckham.
* FakeAustralian: English Nick Stringer as an Australian man who Del sells a car to in "[[Recap/OnlyFoolsAndHorsesS1E02GoWestYoungMan Go West Young Man]]".
* FollowTheLeader: John Sullivan convinced Creator/TheBBC to go ahead with the show based on the success of ''Series/{{Minder}}'', another comedy series about a London wheeler-dealer.
* FriendshipOnTheSet: The cast became close friends, particularly Creator/DavidJason and Creator/NicholasLyndhurst, who would often play pranks onset. Jason described them as "a pair of silly Buddhas" in his autobiography and would call his costar "Nick".
* FunnyCharacterBoringActor: Creator/RogerLloydPack was described by Creator/DavidJason and others as a thoughtful, quiet intelligent man, the polar opposite of Trigger.
* HostilityOnTheSet: Averted as Creator/DavidJason and Creator/NicholasLyndhurst became good friends and the rest of the cast generally got on well, although as a joke on a boring day of filming, Lyndhurst and Jason once decided to fake a huge argument. They also liked to play pranks on Creator/LennardPearce and Buster Merryfield, like convincing the latter that he would have to shave off his famous beard for a flashback scene.
* HypotheticalCasting: In casting the role of Grandad, John Sullivan had in mind an actor similar to Creator/WilfridBrambell, but chose not to use Brambell himself, thinking him too closely associated with ''Series/SteptoeAndSon''.
* IronyAsSheIsCast: Albert smokes a pipe, drinks rum and is terrible at playing the piano. Buster Merryfield was teetoal non-smoker in real life who could play the piano, though he couldn't read music.
* KeepCirculatingTheTapes:
** A downplayed example; while the series is still Creator/TheBBC's best-selling shows of all time on both VHS and DVD, [[ExecutiveMeddling the Corporation's apparent desire]] to [[CanonDiscontinuity eradicate all traces of the original Ronnie Hazlehurst theme tune]] has led to the VHS releases of the first series (which, unlike the DVD, kept the original theme intact) becoming quite sought after by purist fans.
** Due to music licensing laws, the BBC has replaced the original soundtrack on many episodes, and in some cases simply cut out scenes where the offending music is being played. John Sullivan's family [[CreatorBacklash were not happy with the results]]. The law on music licensing has since changed, meaning the original unedited episodes could now be released, but the BBC is yet to do this.
** The same applies to the original version of "A Royal Flush," which is unavailable on any home video format (the VHS release had about a minute of footage removed, and the DVD release removed nearly ten minutes of footage and added a laugh track). However, the original cut still appears from time to time on UKTV Gold and other such channels, so it's not too hard to find decent quality versions of it.
** In a straight version, several mini-episodes such as ''Christmas Trees'', ''Licensed to Drill'' and the ''Comic Relief Special'' have never been released on VHS or [=DVDs=].
* TheMerch: Plenty. Tee-shirts, mugs, money boxes, socks, models of the van...you name it. And, in the true spirit of Del Boy, by no means all of it is officially sanctioned by the BBC.
** On the more [[MisaimedMarketing unusual]] side, a £275 teddy bear was produced for the 40th anniversary of the show, with ads proclaiming that "Del Bear" was a real bargain at [[PaymentPlanPitch only 5 payments of £55 each]].
* OldShame:
** Nearly everyone involved with the show regards "[[Recap/OnlyFoolsAndHorsesS5E07ARoyalFlush A Royal Flush]]" to have been a huge misfire, to the point where John Sullivan admitted in an interview on the day that the show's GrandFinale was broadcast that he wished he had never written it.
** To a lesser extent, Sullivan also wasn't happy with the first Christmas specials, considering "[[Recap/OnlyFoolsAndHorsesS1E07ChristmasCrackers Christmas Crackers]]" to be both rather listless and a re-tread of "[[Recap/OnlyFoolsAndHorsesS1E02GoWestYoungMan Go West, Young Man]]". While the second Christmas special, "[[Recap/OnlyFoolsAndHorsesS2E08DiamondsAreForHeather Diamonds Are for Heather]]", did show that Del can be a family man if he put his mind to it, Sullivan still felt the episode to be a little on the generic side. It wasn't until the third Christmas special, "[[Recap/OnlyFoolsAndHorsesS3E08ThickerThanWater Thicker Than Water]]" that Sullivan tried writing a more significant episode than usual, and then the fourth special, "[[Recap/OnlyFoolsAndHorsesS4E08ToHullAndBack To Hull and Back]]" cemented the feature-length format of the Christmas episodes.
* OneTakeWonder: The famous chandelier gag in "[[Recap/OnlyFoolsAndHorsesS2E07ATouchOfGlass A Touch of Glass]]" was done in one take, mainly because they only had one (very expensive) prop. It was initially intended that this would be the final scene in the episode, so after the incident Creator/DavidJason and Creator/NicholasLyndhurst were required to stand and stare at each other in silence for 30 seconds while the camera rolled. Lyndhurst later recalled that director Ray Butt threatened him with the sack if he ruined the scene by [[{{Corpsing}} laughing]].
* OnlyBarelyRenewed: Due to poor viewing figures, the show was almost cancelled after two series. However, it was repeated in a low key time slot and achieved respectable ratings, which convinced BBC producers to commission another series. The show went from strength to strength thereafter and ironically was continually [[{{Revival}} revived]] during the 1990s and 2000s owing to its status as a ratings winner.
* TheOtherMarty: Creator/LennardPearce pre-filmed the location scenes for "[[Recap/OnlyFoolsAndHorsesS4E03HoleInOne Hole in One]]" just a few days before his death, requiring them to be reshot after Buster Merryfield was hired to play Uncle Albert. In the finished episode, the scenes of Mike looking up at the Trotters are taken from the shoot with Pearce, as only Granddad/Albert's arm and shoulder are visible, and it avoided having to rehire Mike's actor, Creator/KennethMacDonald.
* PostScriptSeason: The show ended after 15 years (7 seasons and four sets of Christmas specials) with the Trotter brothers finding an antique watch in their garage, [[RagsToRiches and becoming millionaires at last]]. The three episode finale, where the Trotters are finally shown in luxury penthouses and expensive sports cars, was shown over Christmas 1996 and attracted massive viewing figures for Creator/TheBBC. A few years later they convinced writer John Sullivan to reprise the ever-popular characters for three more {{Christmas Episode}}s. Having the Trotters [[SnapBack lose their investment money in a stock market crash (based on one in real life) and return to their original lifestyle]] [[DeusExMachina only to gain some of their lost fortune back]] and allow Rodney and Cassandra to finally have a child of their own, the specials were panned by critics and viewers alike, and no more have been produced since 2003. To add salt to the wound, "Time On Your Hands" was featured on [[Creator/{{Sky}} Sky1]]'s often repeated ''Top Fifty TV Endings'' feature... ''completely ignoring the three 2001-2003 specials''.
* RealitySubtext: The deaths of the actors playing four characters were written into the show: Grandad and Uncle Albert were said to have died (and their funerals shown), Mike Fisher was said to be in prison for embezzlement (leading to Sid taking over the Nag's Head), and Denzil's wife Corrine was said to have finally divorced him.
* TechnologyMarchesOn: A lot of the stuff Del flogs is extremely quaint now, such as huge camcorders, [=VCRs=], old computers, etc.
* ThrowItIn: Trigger wasn't supposed to be in the famous scene where Del falls through the bar in "[[Recap/OnlyFoolsAndHorsesS6E01YuppyLove Yuppy Love]]". Creator/RogerLloydPack was rehearsing for a different TV programme in the same building. On a break he wandered into their rehearsal room to say hello and told John Sullivan he was free if he needed him. Sullivan wrote him in straight away and he was part of the scene.
* TroubledProduction: The 1986 ChristmasSpecial "[[Recap/OnlyFoolsAndHorsesS5E07ARoyalFlush A Royal Flush]]" had a very troubled production:
** Creator/DavidJason, Creator/NicholasLyndhurst and Buster Merryfield left production in Dorset to make an appearance at the Royal Variety Performance, putting the episode behind schedule. Jason lost his voice and needed three days off to get it back. This was the only time Jason ever called in sick on an episode of the show. As soon as he recovered, Lyndhurst came down with the flu, throwing the production into a panic.
** There was no more time for edits so it couldn't be played before a studio or live audience, leaving the episode with no laughter track and no music. It got so close to the deadline that the final scene was nearly broadcast live on Christmas Day, 1986, a nerve-wracking prospect, what with performing the scene to 19 million viewers, and would have wrecked the cast's Christmas plans. Whenever anyone asked questions during the production chaos, the answer they got was "Fuck knows!"
** It was finished at the very last minute with editing continuing into the early hours of Christmas morning. Jason likened it to Santa's elves on amphetamines to get the episode finished on time. In the end, he thought it was patchy, but he was not surprised, just relieved it got made.
** When the episode aired, it got widely negative reactions which would have long-term repercussions for the series. The following year's ChristmasSpecial, "The Frog's Legacy" ended up being written as a [[SeriesFauxnale potential finale]] due to concerns that the show was running out of steam, and while the decision was made to carry on, the show got a major ReTool. Most of the cast and crew would go on to consider "A Royal Flush" to be the show's worst episode, with series creator John Sullivan openly admitting in a 2003 interview that writing the episode was his biggest regret about his time on the show.
* UnfinishedEpisode: There were plans for a final episode to commemorate the show's 30th anniversary. Del Boy, now aged 65 and a millionaire, would have announced in the Nag's Head that he was retiring. However, John Sullivan became ill while writing the script and died before he had completed it.
* WagTheDirector: Creator/DavidJason vetoed ideas that Del should have a perm, thick Music/ElvisPresley sideburns or gold sovereign rings on each finger (just two on each hand instead) because they were parodistic and not the right way to go. Instead of a perm, Del had tidy hair with a bit of grease.
* WhatCouldHaveBeen:
** Or what could have not been. Due to disappointing viewing figures for the first two series, the show was nearly cancelled altogether. However, the first and second series were repeated in a low key time slot in June 1983 and achieved respectable ratings, which convinced BBC producers to commission a third series. The show went from strength to strength thereafter.
** John Sullivan intended for Music/ChasAndDave to sing the show's theme song due to the success from their "Rockney" style of music (a mixture of rock 'n roll and cockney). However, they were unavailable having just recorded their hit single "Ain't No Pleasing You", so Sullivan sang the song himself after being persuaded by Ray Butt to do so. A reworking of Chas & Dave's song "Margate" was used for "[[Recap/OnlyFoolsAndHorsesS6E07TheJollyBoysOuting The Jolly Boys' Outing]]".
** In 1986, Creator/DavidJason told John Sullivan that he wanted to leave the show and further his career elsewhere, so the fifth series finale "[[Recap/OnlyFoolsAndHorsesS5E06WhoWantsToBeAMillionaire Who Wants to Be a Millionaire?]]" was written as the final OFAH episode, and would have seen Del leaving England with his friend Jumbo Mills to run a car business in Australia. An AfterShow entitled ''Hot Rod'' was planned, which would've been all about Rodney running Trotters Independent Traders with Mickey Pearce. However, Jason changed his mind and decided to stay on, and Sullivan rewrote the ending to show Del rejecting Jumbo's offer.
** The TroubledProduction and poor reception of 1986's Christmas special, "[[Recap/OnlyFoolsAndHorsesS5E07ARoyalFlush A Royal Flush]]" caused outgoing producer-director Ray Butt to tell John Sullivan that the show had run out of steam, and to let it end with the following year's Christmas special, "[[Recap/OnlyFoolsAndHorsesS5E08TheFrogsLegacy The Frog's Legacy]]". Sullivan did consider doing this, but ultimately decided against it after "The Frog's Legacy" got a much better reception, though he did give the show a major {{retool}} afterwards.
** John Sullivan originally wanted to make Cassandra a girlfriend of Trigger, Denzil or an admirer of Boycie, but decided that like he planned to do with Del, Rodney needed a long term relationship.
** An American remake of the show was once said to be in the works, but never surfaced.
** In the first chapter of the early 2000s trilogy, "[[Recap/OnlyFoolsAndHorsesS9E01IfTheyCouldSeeUsNow If They Could See Us Now]]", The BBC wanted to get the rights from ITV to use the actual ''Series/WhoWantsToBeAMillionaire'' gameshow with a special guest appearance from Chris Tarrant, but ITV refused because a key plot point was that Del gives a correct answer which the quizmaster erroneously says is wrong. They ended up with a blatant {{expy}} called ''Goldrush'', hosted by Creator/JonathanRoss.
** Creator/ElizabethHurley auditioned for Cassandra.
** Creator/AnthonyHopkins was keen to appear in the show, as he was a big fan. John Sullivan even wrote the part of [[LondonGangster Danny Driscoll]] for him in the 1989 episode "[[Recap/OnlyFoolsAndHorsesS6E06LittleProblems Little Problems]]", but filming clashed with ''Film/TheSilenceOfTheLambs'' and he therefore had to pull out.
** After Creator/LennardPearce's death, John Sullivan considered introducing an elderly female relative, named Auntie Doris, who would come to live with the Trotters and had a similar personality to Uncle Albert but this was vetoed by David Jason who was uncomfortable being rude to an old women, in addition that John Sullivan reckoned he could write a lot more cunning dialogue if the character was a man.
--->'''David Jason''': You couldn't say, "Shut up you old git" to a woman or bundle her into the back of the van.
* WordOfSaintPaul:
** Creator/DavidJason always suspected that Uncle Albert's war stories were fake.
** Creator/RogerLloydPack stated that Trigger, while not intelligent, believed that he had an insight into life. He suggested that Trigger felt excluded as a child and found his status by saying things that made people laugh.
* WorkingTitle: John Sullivan originally named the show ''Readies''.
* WriteWhatYouKnow: Most of the show's storylines were based on events in the life of creator John Sullivan and/or members of his family. Similarly, Del Boy's characterization was essentially a combination of Sullivan's father and the show's initial producer-director, Ray Butt (who Sullivan had previously worked with on ''Series/CitizenSmith'').
* YouLookFamiliar: Jumbo Mills, Del's old friend and business partner in "[[Recap/OnlyFoolsAndHorsesS5E06WhoWantsToBeAMillionaire Who Wants to Be a Millionaire]]", is played by Nick Stringer, who also appeared in "[[Recap/OnlyFoolsAndHorsesS1E02GoWestYoungMan Go West Young Man]]" as an Australian to whom Del sells a car with faulty brakes
