* TheCharacterDiedWithHim: Betty Driver died aged 91, so her character Betty Williams was killed off as well. This has happened several times: Jack Walker, Jerry Booth, Albert Tatlock, Stan Ogden, Bert Tilsley, Blanche Hunt. Elsie Tanner and Christine Hardman were both mentioned as having died several years after they left the show and Annie Walker is talked about in the past tense.
* CrosscastRole: The unseen character "Fat Brenda" was played by Steve Huison in a spin-off stage production ''Fat Brenda - My Flamin' Story''.
** Liam Connor Jr. was played by Imogen Moore when he was born.
** Similarly, Harry Platt was played by twin girls as a baby.
* TheDanza: Betty Driver as Betty Williams (née Turpin).
* DawsonCasting:
** Nick Tilsley's current actor, Ben Price, is ''ten years older'' than his character's age.
** While Sunita Alahan was born in 1978, Shobna Gulati was born in 1966.
** Helen Worth who plays Gail was born in early 1951 while the character was born in 1958. To contrast, Gail's Mother Audrey is three years older than her actress Sue Nicholls (born late 1943). In other words, there is only a seven year age difference in real life between onscreen mother and daughter.
** 19-year-old Lucy Fallon started playing 14-year-old Bethany Platt in 2015. The heavy amount of make-up that Bethany liked to wear made the age difference ''very'' noticeable. Also worth noting that Bethany was originally going to be played by Katie Redford who was 25 years old at the time.
* DisabledCharacterDisabledActor: The show has had a few wheelchair-using characters in its time, though previously they were played by able-bodied actors. Currently, however, both Izzy Armstrong and actress Cherylee Houston, who plays her, suffer from a rare connective tissue disorder, Type III Ehlers-Danlos syndrome.
* DuelingShows: With ''Series/EastEnders''. Although they don't broadcast opposite each other, in the UK you're either a fan of one or the other. [[TakeAThirdOption Or both]].
* FakeIrish: A borderline example with the Connor family. While Michelle, Liam and Paul were presumably reared in England, they were born to Irish parents and seem to have kept close contact with Ireland (their parents returned to Dublin to live). Of the three, only the actor playing Paul had any known Irish ancestry and even his parents were English-born.
* FakeNationality:
** Collins has a natural London accent. Opinions vary on how good/bad her Manchester accent is.
** Karl Munro's actor is Scottish.
* FanNickname:
** Deirdre Barlow has the following:
*** ''The Weatherfield One''.
*** Dreary.
** Tracy Barlow has Tracyluv.
** Owen Armstrong has Creator/RickyGervais (due to his likeness to said).
** Asha and Aadi Alahan have Asda and Aldi. Gloria Price even [[CrowningMomentOfFunny accidentally called them this]] in 2013.
* HideYourPregnancy: An actress playing a post-op transgender woman become pregnant; it started with the character sitting down a lot, and later she went on holiday to keep things from getting too obvious.
* IAmNotSpock: Helen Flanagan, aka Rosie Webster.
* NamesTheSame: David Platt. If you don't get it, just Google it.
* TheOtherDarrin:
** Tracy Barlow. Played by various actors, with Dawn Acton and Kate Ford being two of the best-known.
** Tracy's step-brother Peter has been played by seven different actors. Two have even appeared as completely different characters including Ken's ''other'' son.
** Tracy's daughter Amy holds the show's record of the most actors to play a character with a total of eight actresses. Most of these actresses however, were babies or toddlers at the time and weren't even old enough to read lines or really understand what was going on.
** Most of the characters introduced as children.
** Nick Tilsley. ''Twice'', and both times as an adult.
** Averted with Chesney Brown -- Sam Aston has played the character from a child to an adult.
* PlayingAgainstType: Andrew Sachs, best known as Manuel from ''Series/FawltyTowers'' appeared as a ShrinkingViolet dying of a brain tumour.
* PostScriptSeason: Probably the ultimate example -- it has essentially been on a series of postscript seasons since ''1961''. It was originally intended to be thirteen episodes long, with Coronation Street bulldozed in a [[MadeForTVMovie Made-for-TV Movie.]] However, it proved so popular that a new series was commissioned, and it's been broadcasting more or less continuously to the present day.
* RealitySubtext: Sally Webster was scripted to reveal to her husband Kevin that she had cancer on Christmas Day, 2009. The storyline prompted Sally Dynevor, the actress playing her, to see a doctor and undergo tests for the disease in order to research the role. [[TearJerker Sally found out she had cancer hours after filming the scene where she told Kevin about the cancer]], so when they shot the scenes where they told their on-screen daughters, [[EnforcedMethodActing the tears were real]]. The storyline was rewritten so that the actress was off-screen for six months whilst she was undergoing chemotherapy and radiotherapy.
* RealLifeRelative:
** Linus and James Roache, the real life sons of Bill Roache (who plays Ken Barlow) played his son and his grandson, respectively.
** Brooke Vincent (Sophie Webster) and Ellie Leach (Faye Windass) are cousins in real life.
** William Rush, who appeared in 2014 as one of the lads that bully Maddie in her room in the homeless hostel, is the real life son of Debbie Rush (who plays Anna Windass).
* RecycledScript:
** Many fans and critics have noted that when the Windasses made their debut in 2008 that they and their circumstances were a bit too similar to the Battersbys, i.e., the "family from Hell", who made their debut over a decade earlier.
** Steve having a baby outside of his current marriage has been done twice: first in 2004, when he got Tracy pregnant while he and then-wife Karen had broken up, but remarried that same year and became pregnant with a child that she miscarried and then again in 2017, when he got Leanne pregnant while he and then-wife Michelle were separated but soon reconciled, became pregnant with their own child and that pregnancy also ending in a miscarriage.
** The storyline involving [[spoiler: Daniel]] pushing Ken down the stairs is nearly identical to the storyline of David pushing Gail down a flight of stairs. Also, both incidents happened for the same reason: [[spoiler: a strained relationship with the parent and the latter convincing the former's girlfriend to get an abortion,]] only the earlier storyline was not a Whodunit.
** Pat Phelan becoming a killer resembles Richard Hillman storyline from 15 years ago. Phelan [[spoiler: allowing Michael to die at a building site]] is similar to Richard leaving Duggie to die. This was then followed up by Phelan [[spoiler: committing his first murder by killing Andy Carver]], similar to Richard's first proper murder being his wife. Funnily enough, Phelan killing took place before his wedding, just like Richard's first killing took place before his wedding.
* RoleEndingMisdemeanor:
** Averted with William Roache (Ken Barlow) & Michael [=LeVell=] (Kevin Webster) - both characters were written off the show whilst their actors were awaiting trial for sexual offences. Both actors were found not guilty, allowing the show to bring them back to the show.
** Bruce Jones (Les Battersby) was written out after allegations of drunkenness and inappropriate comments in the presence of an undercover reporter.
** Chris Fountain (Tommy Duckworth) was abruptly fired after a homemade rap video where he sang about rape was discovered online.
** Marc Anwar (Sharif Nazir) was dropped from the show in September 2016 after making negative comments about India (as Anwar was born in neighboring country Pakistan) on Twitter. The actor alleged that his contract was going to be up soon anyway, so was only dismissed early; either way he was dropped earlier than expected.
** Katie Redford (Bethany Platt) before she even started filming her first episode. She was fired from the role when fans on the ''Digital Spy'' forum uncovered evidence that she had lied about her age. She was replaced with Lucy Fallon.
** Bruno Langley (Todd Grimshaw) was fired after being charged with sexual assault in October 2017. Todd's disappearance was explained by having him punch a police officer off-screen.
* RomanceOnTheSet:
** Tina O'Brien (Sarah Louise Platt) dated Bruno Langley (Todd Grimshaw), the couple splitting up before their characters began dating.
** She then began dating Ryan Thomas, who plays Jason Grimshaw, Todd's brother and Sarah Louise's future husband.
** A more successful pairing is between Alan Halsall, who plays Tyrone Dobbs, and former Corrie actress Lucy-Jo Hudson, who played Katy Harris from 2002-2005, who have been married since 2009 and welcomed a baby girl four years later.
* ThrowItIn: When the title sequence was redone in the 1970s, the film crew did not notice that a cat has found its way onto the set. It's been a fixture of the show ever since.
* TooSoon:
** The show changed a storyline in which a character's baby was abducted due to similarities with the Madeline [=McCann=] abduction case.
** The episode scheduled to air on the 2nd June 2010 was cancelled by Creator/{{ITV}} due to the then-breaking news about the Cumbria massacre. The episode in question featured scenes with guns.
* WhatCouldHaveBeen:
** Upon both Tracy and Peter's returns in the early 2000s, there were talks for them to [[BrotherSisterIncest become involved with one another]] and Tracy to become pregnant as a result of the affair. This, thankfully, never came about, due to some very [[{{Squick}} obvious reasons.]]
** Bet Lynch was going to become manageress of the Rovers Return following her 2002 return. However this never came about as Julie Goodyear dropped from the show due to health reasons, meaning the character was only on-screen for a couple of weeks and left suddenly off-screen.
*** After the death of her old colleague and friend Betty Driver in 2011, Julie Goodyear expressed interest in reprising the role of Bet Lynch for a one-off appearance for the character Betty's funeral. However the producers didn't take her up on the offer (despite numerous rumours about them wanting to bring her back), which led to only Betty's son Gordon Clegg (played by Bill Kenwright) returning for the funeral.
** Also, there was supposed to be a conclusion to the Maya Sharma storyline involving a trial against her, but was left unresolved due to some personal reasons involving Jimmi Harkishin, who plays Dev Alahan.
** Creator/LaurenceOlivier was once offered a guest role.
** For the 50th Anniversary Special in 2010, producers attempted to lure back Jean Alexander to reprise her iconic role of Hilda Ogden, and even tried to tempt her with a huge salary for just one episode. But Jean turned down the offer, although was down to her wanting to keep Hilda's legacy intact.
** Creator/JohnNathanTurner wanted to produce the series and his agent put his name forward to be considered, but he was unsuccessful. Nathan-Turner said prior to his death that he was a particular fan of the series and not becoming producer was his biggest unfulfilled ambition.
** Although Stephanie Cole (Sylvia Goodman) was going to leave the series, she was meant to remain throughout Hayley's cancer storyline and bring some caustic charm to the screens during the story. However after suffering a personal loss, she ended up leaving much earlier, meaning the character was suddenly written out and absent during the storyline.
* WorkingTitle: Tony Warren had to rename the series from its original title ''Florizel Street'', which was considered to sound like a disinfectant.
* WrittenInInfirmity: Sally Webster had a storyline where she battles breast cancer. Turns out that the actress who plays her, Sally Whittaker, ''discovered she had breast cancer as a result of researching the storyline for the role''. She says that she would never have noticed if the storyline hadn't been given to her, so [[CrowningMomentOfAwesome the show effectively saved her life]].
