Re-watchingSex and the Cityin 2018 can be a truly eye-opening experience.

You’ll realise the Season One wardrobe is basically everything you’re seeing in stores this year.

You’ll probably cringe at the outdated jokes and attitudes (Carrie’s reaction to bisexuality… oooof).

How, exactly, did Carrie afford all her designer clothes? The mystery remains. (Image: HBO)

You'll definitely question how Carrie ever afforded her fabulous urban lifestyle on one weekly newspaper column and the occasionalVoguefeature.

You'll also do alotof double takes.

Throughout its six seasons,Sex and the Citygave plenty of up-and-coming actors their break into the world of TV - and some of them have gone on to become big, big stars in their own right.

Here are just some of the famous faces you probably didn't notice in the background... and some of the famous faces you simply forgot had a cameo.

Justin Theroux

The haircut makes all the difference. (Image: HBO)

You're about to feel pretty silly, because Justin Theroux played TWO ENTIRELY DIFFERENT PEOPLE in the show and somehow got away with it.

TheGirl on the Trainstar (and Mr. Jennifer Aniston) first appeared in Season One as Jared, a fellow writer who was named as one ofNew York Magazine's Coolest People Under 30 alongside Carrie.

He then showed up in Season Two as her one-time boyfriend Vaughan - also a writer - who had the perfect family but a few... shortcomings.

Bradley Cooper

"IS THIS YOU?" Never forget. (Image: HBO)

SATCgave Bradley Cooper his first-ever on-screen role - and a "nightmare" kiss with Sarah Jessica Parker (he was very nervous about shooting it, you see).

The actor appeared in Season Two as Jake, in the episode with Carrie's infamous 'Single and Fabulous?'New York Magazinecover. Not a particularly great guy, in the end.

Matthew Morrison

Oh yeah. That guy. (HBO)

Long before Matthew Morrison played teacher Will Schuester inGlee, he was an extra inSATC. No, really — his was a blink-and-you'll-miss-it role as a waiter serving Carrie. Incidentally, he starred in the same episode as Bradley Cooper.

John Slattery

That time Carrie got into politics. (HBO)

Mad Menfans know him best as the charming Roger Sterling, but John Slattery also took his turn as one of Carrie's boyfriends — would-be politician Bill Kelley. If that doesn't ring a bell, the quote 'to pee or not to pee?' might.

Gabriel Macht

Oh hey, Harvey Specter. (HBO)

Here's another one who went on to be a TV leading man in his own right.Suits' Gabriel Macht showed up right at the start ofSATC's reign, in the very second episode, as an artist and serial "modeliser" named Barkley. (Is that even a real name?)

Elizabeth Banks

May the (dating) odds be ever in your favour. (HBO)

The woman we now know best asThe Hunger Games' Effie Trinket and the director ofPitch Perfect 2played a bit role as Catherine, a politician's fiancee at a party thrown by Bill Kelley (John Slattery's character). Catherine gave Charlotte the idea for her 'bring a date you're not interested in' party.

Bobby Cannavale

Remember the wheatgrass shots? (HBO)

If any of these cameos are going to jog your memory, it has to be Adam - aka Samantha's 'funky spunk' guy.

The role left a bad taste in everyone's mouth, but it hasn't done Bobby Cannavale any harm. The actor has since gone to star in TV showsNurse Jackie,Cold Case,Boardwalk Empire,Mr RobotandMaster of Noneand movies such asBlue Jasmine.Oh, and he's also married to Rose Byrne.

Will Arnett

The look of love. (HBO)

These days, Will Arnett has a long list of on-screen credits and Emmy nominations to his name (and was also married to Amy Poehler for nine years, but it's too sad to talk about). But he too played a small role as one of Miranda's lovers - one with a penchant for getting caught.

Kat Dennings

A not-so-broke girl. (HBO)

She's now one of thoseTwo Broke Girls- among other roles - but Kat Dennings played the exact opposite onSex and the City. Her 13-year-old character Jenny Brier was rich, bratty, and even gave Samantha a run for her money.

Donald Trump

Oh... it's you. (HBO)

Chances are you willingly wiped this cameo from your mind, in which case I apologise for reminding you of it.

Trump appeared as himself in the show, and even earned a name drop from Carrie Bradshaw herself: "Samantha, a Cosmopolitan and Donald Trump. You don't get more New York than that."

I couldn't help but wonder... what would Carrie think if she knew about last year's election?
