'''''The Persuaders!''''' is a 1971 comedy/adventure series starring Tony Curtis and Creator/RogerMoore.

Lord Brett Sinclair, a [[QuintessentialBritishGentleman British gentleman]] and [[BlueBlood aristocrat]] and Danny Wilde, a NouveauRiche American SelfMadeMan, are a pair of BrilliantButLazy [[MillionairePlayboy playboys]]. Thanks to the machinations of ex-judge Fulton who wants to give their lives a new sense of purpose, they wind up as best friends and [[TheRival rivals]] who go on various adventures and take on criminal cases on an odd-job basis. Much of the humor of the series comes from the witty banter between the two characters as they constantly criticize each other's habits and lifestyle.

While the series did only moderately well on the home British/American market (which should not be ''too'' much of a surprise, considering that the main characters are based on their blatant national stereotypes) it has done significantly better abroad, and is widely remembered and cited in many European countries; most notable is it success in Germany, where the dialogues were rewritten more than they were translated, with much more BreakingTheFourthWall and the likes, essentially making it into a different series entirely.
!!''The Persuaders!'' provides examples of the following tropes:

* ChronicEvidenceRetentionSyndrome: An episode involves a crucial piece of evidence that the culprit couldn't work the will to destroy, despite his henchman's urging: A gift by UsefulNotes/AdolfHitler himself for helping the defeat and surrender of France.
* CostumePorn: The clothes of Lord Brett Sinclair were selected with greatest care by Roger Moore himself. The more dynamic style of Danny Wilde's fashion, featuring leather jackets, flares and scarfs, had its finger on the pulse of the 70's and led to Curtis' being voted "Best Dressed Man" of 1970.
* DrinkOrder: No particular one for either, but several very fancy ones show up, frequently with arguing over seemingly-quibbling details of the recipe.
* ErmineCapeEffect: PlayedForLaughs in the very beginning of the 3rd episode, "Take Seven"; Brett has put on his regalia as an Earl since he is about to attend the opening of parliament, much to the amusement of Danny.
* ExcitedShowTitle
* GagDub: Thanks to Rainer Brandt, the German dub borders on this and became a much bigger hit than the original.
* GentlemanAdventurer: Lord Brett Sinclair.
* GirlOfTheWeek
* HeterosexualLifePartners: Danny and Brett, obviously.
* NoFourthWall: The German dub is famous for doing this, with Danny in particular standing out. In one episode, after Brett had just made an especially lame pun, Danny tells him to stop talking like that lest the ZDF (the German TV channel that dubbed and aired the series) cancel the whole show, and that's just the tip of the iceberg.
* ReedRichardsIsUseless: One episode had the formula of a perfect, easy-to-manifacture substitute for gasoil as the MacGuffin. For obvious reasons, it could not be made public at the end of the episode if they didn't want to ToneShift into a TwentyMinutesIntoTheFuture show, so they contrived elements so that burning the formula seemed a virtuous, reasonable thing to do for the heroes. (It isn't convincing at all, though.)
* {{Redubbing}}: In order to increase the popularity of the show in English-speaking countries, the dialog style of the German dub was applied to the English version in some broadcasts, though it is the original version that has been released on DVD.
* RedOniBlueOni: Even in the opening titles, Sinclair is Blue and Wilde is Red.
* RunningGag: Brett has a habit of regaling others with lengthy tales about his many, many, [[RuleOfThree many]] ancestors, usually to his involuntary listeners' exasperation.
* SelfMadeMan: Danny Wilde is said to have "earned and spent away" several considerable fortunes.
* SexyStewardess: Brett Sinclair's own private flight attendants were also obviously hired for their looks and their, er, friendliness.
* SuspectExistenceFailure: Subverted in an episode where Brett's relatives are being murdered: all the suspects die... then it's revealed that one of them was actually the murderer, and faked his death because he knew that would clear him.
* TheyFightCrime
* ToneShift: ''The Persuaders!'' as seen by American and British audiences is a relatively serious series, with a light-hearted side provided by the main characters, but not ''centered'' on comedy. Rainer Brandt's famous German dub, however, turned it into a wacky, pun-laden comedy.
* UncannyFamilyResemblance: In episode "A Death in the Family", which is a tribute to ''Film/KindHeartsAndCoronets'', Roger Moore plays three members of his usual character's family, including a woman. This is Lampshaded at the end when Danny Wilde's aunt arrives, played by... Tony Curtis.
* WorldOfPun: Led by the German dub.
* YouHaveOutlivedYourUsefulness: In an episode, Danny Wilde manages to [[HeelFaceTurn recruit]] an actor impersonating a dead millionaire by warning him of what might happen when his employers don't need to hide the millionaire's death anymore.
