* BritishAccents: In what may be the finest British Accents twist of all time, author Bernard Cornwell revised the backstory of the character Sharpe to reflect Sean Bean's portrayal. The books had established that Sharpe was from [[LondonTown London]], but Bean is from Sheffield and has a distinct [[OopNorth Northern accent]]; Cornwell [[RetCon established in later novels]] that while Sharpe had indeed been born in London, he fled to Sheffield for a life of crime to avoid being sold as a chimney sweep by the person that ran his orphanage.
* TheOtherDarrin: Wellesley is played by David Troughton. His elevation to the peerage not only changes his name to Wellington, but his actor to Hugh Fraser.9
* ReferencedBy: See ReferencedBy.{{Sharpe}}.
* RetroactiveRecognition[=/=]HeyItsThatGuy: Happens a lot watching the older TV episodes nowadays, because of many actors in early roles who went onto greater and/or geekier things:
** Sean Bean himself is better known worldwide for his later roles such as 006 in ''Film/{{Goldeneye}}'', Boromir in ''Film/TheLordOfTheRings'' and Ned Stark in ''Series/GameOfThrones''.
** [[Film/{{Manhunter}} Brian]] [[Film/X2XMenUnited Cox]] as Major Hogan, Lord Wellington's spymaster.
** Creator/DanielCraig as Lieutenant Berry, a lecherous and violent minor villain. Bonus points for having a future Film/JamesBond fight [[Film/{{Goldeneye}} a future Bond villain]] [[spoiler:(and losing for failing to shoot his nemesis when he has the chance)]].
** PetePostlethwaite as Obadiah Hakeswill, Sharpe's archnemesis from his days in the ranks.
** [[AustinPowers Elizabeth Hurley]] as one of Sharpe's love interests, Lady Farthingdale.
** [[Film/StarTrekFirstContact Alice Krige]] as FemmeFatale French spy, La Marquesa.
** [[Series/TheNewsroom Emily Mortimer]] as a traumatised mute novice.
** MarkStrong as a British officer, in-universe MemeticBadass and traitor.
** [[Series/BuffyTheVampireSlayer Alexis]] [[Series/{{Angel}} Denisof]] as a rich male appendage who steals Sharpe's woman.
** [[{{Pointless}} Alexander Armstrong]] played the same part in a couple of episodes beforehand.
** [[Series/LifeOnMars2006 Philip]] [[AshesToAshes Glenister]] as Matt Truman, a workers' rights leader [[spoiler:and Sharpe's long-lost half-brother]].
** [[{{Primeval}} Douglas Henshall]] as the wicked cavalier, George Wickham.
** Henshall's ''{{Primeval}}'' costar and love interest Lucy Brown appears in one of the later episodes in India.
** Paul Bettany as Prince William of Orange. Not the last time he would [[Film/MasterAndCommander fight in the Napoleonic War]].
** [[IndianaJonesAndTheLastCrusade Colonel Vogel]] or if you prefer [[Film/HarryPotterAndTheDeathlyHallows the older Gellert Grindelwald]], Micheal Byrne appears as spymaster Major Nairn.
** [[OneFootInTheGrave Mr Sweeny]] shows up in ''Sharpe's Waterloo'' as one of the Duke of Wellington's relations.
** Hey, lots of guys and one gal later appeared on ''Series/{{Hornblower}}''.
*** Josefina, a Spanish aristocrat, is Senora Ortega (Katia Caballero).
*** Major Nairn is dying Captain Keene (Michael Byrne).
*** Colonel Fletcher is Lieutenant Buckland (Nicholas Jones)
*** Matt Truman is Gunner Hobbs (Philip Glenister).
*** Mr Tapling of the diplomatic service is Runciman (Ian [=McNeice=]).
*** Napoleon, Boney himself, is Steward James Doughty (Ron Cook). Holly crap, no wonder sailor Styles hated him so much.
* WhatCouldHaveBeen: [[Film/WithnailAndI Paul]] [[Series/DoctorWho McGann]] was originally cast as Richard Sharpe, but he broke his leg while playing football only a few days into the shooting of ''Sharpe's Rifles''. Sean Bean was recast in the role and... well, you know the rest.
* WriterRevolt: An editor told Bernard Cornwell to change a scene where an Ensign died likely because ensigns are frequently young boys or men in their mid to late teens. He resented being told how to write, so he changed it to be ''more'' depressing. And in a number of the books since, Cornwell has killed off Ensigns in increasingly worse ways.
* WritingByTheSeatOfYourPants: Cornwell does plan his novels in advance, but has admitted to changing them up midway through because he thinks it reads better. An example - Frederickson was supposed to marry Lucille in ''Sharpe's Revenge''.
