In the space of six short years, ‘Sex And The City’ grew from a cult favourite to one of the most impactful and influential TV shows of the 20th century, and it definitely didn’t have to look far for celebrity guests to put in appearances.
By the time its sixth and final series aired in 2001, A-list stars were pretty much queuing up to land a role, either as one of the girls’ love interests or in a cameo appearance as themselves.
More interesting, though, is just how many of its supporting actors have gone on to make the big time much later on in their careers, after appearing for brief stints in ‘Sex And The City’.
Here are 18 of the big names whose ‘Sex And The City’ appearances might have passed you by...
Bradley Cooper is one of several A-listers who appeared in 'Sex And The City' during its six-series run, but he's one of the few who did it before he made it big.
Here he is about to ruin Carrie's night in 'They Shoot Single People, Don't They?', thrusting an unflattering photo on the cover of a magazine in her face.
Years before 'Mad Men', John enjoyed a two-episode stint as a politician, who woos Carrie when the two of them judge a 'hottest firemen' competition on Statten Island.
Their relationship turns sour quickly, though, when he decides her sex column is bad for his image, and she decides she doesn't want to urinate on him for sexual kicks.
A tale as old as time.
Kat was just 14 years old when she made her TV debut in 'Sex And The City', playing Jenny Brier, a spoilt brat for whom Samantha helps plan a Bat Mitzvah.
Though the girls are initially jealous that she's so privileged and confident as a teenager (and Miranda is jealous of her friend's sapphire braces), they eventually all learn an important lesson about the importance of working hard to get places.
'SATC' bosses were clearly so impressed with Justin that they had him play two roles in the show.
In series one, he plays Jared, an obnoxious author Carrie flirts with at a party in a bid to make Mr Big jealous.
Two years later, he played Vaughn, a short story author whose family Carrie is really taken by, even though the man himself has his shortcomings (including, as Samantha would suggestively say, in the bedroom).
Four years before his big break in 'Arrested Development', Will's first small screen role was as a romantic interest for Miranda in 'SATC', who enjoys having sex in places he can get caught.
In 'Sex And Another City', the girls take a trip to LA, where Carrie meets a man she's led to believe is an agent. Turns out he's actually a house-sitter.
Here's the moment he gets rumbled by none other than Carrie Fisher, playing herself, in the days before she became Queen Of Twitter.
So obviously this wasn't before he became famous, but it was long before he became within arm's reach of succeeding Barack Obama as US President.
In 'The Man, The Myth, The Viagra', he's shown as a pal of Ed, the elderly man Samantha eventually takes to bed, before binning him off when she catches a glimpse of his bare bum.
She probably should have dumped him the minute she saw who his friends were, in hindsight.
Golden Globe nominee Blair has gone on to star in 'L.A. Law', 'In Treatment' and 'Dirty Sexy Money', but to 'Sex And The City' fans, he'll always be Dr Robert Leeds.
In 'Politically Erect', Elizabeth makes an ever so brief appearance as Catherine, so early in her career she's actually billed as Elizabeth Maresal Mitchell.
Now best known for his role in 'Third Watch', and as Will's boyfriend in 'Will And Grace', there was a time when Bobby's face was best known as the man with *sigh* "funky-tasting spunk". According to Samantha, at least.
Now a two-time nominee for her portrayal of Elsbeth in 'The Good Wife', Carrie also once played an interior decorator in 'Sex And The City', who stole Miranda's love interest right from under her.
She did give her that sculpture of dancing frogs, though, so she wasn't all bad.
Incidentally, Carrie Preston is also what lead 'SATC' character Carrie Bradshaw became known by after marrying Mr Big in the first film.
'Grey's Anatomy' star Chandra Wilson's 'Sex And The City' appearance was ever so brief, but nonetheless memorable.
You might remember her as the police officer who tries to stop Samantha from covering a lamppost in defamatory posters about Richard... until she discovers she'd caught him "eating another woman's sushi", that is.
'Sex And The City' was Eddie's very first TV credit in 'Boy, Girl, Boy, Girl'. One of the most dated episodes of 'SATC', Carrie is visibly uncomfortable to learn the man she's dating is bisexual. She does wind up kissing Alanis Morrissette later on, for reasons we're still not totally clear about.
You know what? Ron can do 'Boardwalk Empire' and he can do 'Standoff'... but to be honest, whenever we see him, we're just reminded that he broke up with Carrie on a Post-It.
Not here for it.
Thought Miss Claudette looked familiar when you watched 'Orange Is The New Black' for the first time?
You probably remember this scene, in which actress Michelle Hurst briefs Samantha, ahead of an STD check.
Dean starred in the episode 'The Fuck Buddy' as Carrie's... well... you can probably guess what, actually.
He and Sarah Jessica Parker crossed paths once again more than a decade later, when he starred in her new show 'Divorce', also on HBO.
The 'Glee' actor's 'Sex And The City' appearance truly was blink-and-you'll-miss-it - he doesn't even have any lines.
Instead, he plays a busboy in a restaurant where Carrie is trying to enjoy her own company and have a meal by herself.
Yeah, we know, this wasn't before she was famous. We just like reminding ourselves that this happened, to be honest.
