These hidden details in Netflix's Too Much will change how you watch it.

Viewers have fallen head-over-heels for Netflix's Too Much, a hilariously sharp romantic comedy series from creator Lena Dunham and her husband, Luis Felber.

The story centres on Jessica, a chaotic New Yorker played by Hacks star Megan Stalter, whose life is upended when a seven-year relationship with her ex, Zev (Michael Zegen), collapses.

Deciding to leave her troubles — and her ex's new Instagram-famous fiancée (Emily Ratajkowski) — behind, Jessica transfers to London.

It's here she forms an unexpected connection with Felix, an offbeat musician portrayed by Will Sharpe who shows her the best (and worst) of London.

It's a classic expat rom-com, and one of the best in recent memory.

Too Much features a damn excellent ensemble including Rita Wilson, Lena Dunham and Naomi Watts, with delightful guest appearances by Jessica Alba, Kit Harington, Rita Ora and Andrew Scott.

But what truly sets Too Much apart is all the clever Easter eggs and references to the iconic romantic comedies of yesteryear.

Lena Dunham wanted to pay homage to her favourite rom-coms and cinematic tropes. "For me, romantic comedies are not about the idea that you need to be in a couple to be a fully formed person. They're really about the idea of self-acceptance and finding someone who accepts you," she told the Irish Examiner.

"The best rom-coms, whether it's When Harry Met Sally, or Four Weddings and a Funeral, that's really what they're offering, a sense that there is a place in the world for you, and that's really what we wanted to do."

The series not only references iconic films like Notting Hill and Bridget Jones's Diary, but it also subverts the familiar tropes in these movies.

Here are all the Easter eggs we spotted in Too Much. Happy hunting!

Lena's character is literally named Nora.

Dunham plays Jessica's sister Nora in the series, and the name choice was no accident.

When it comes to rom-coms, there is one woman widely regarded as the queen of the cinematic rom-com: Nora Ephron.

Nora's scripts are celebrated for their sharp wit and rich characters. Her movies created the blueprint for the genre, writing true gems like When Harry Met Sally, Sleepless in Seattle and You've Got Mail.

The names of the episodes.

Every episode of the series is named after an iconic rom-com or romantic drama, including 'Pity Woman' (Pretty Woman), 'Notting Kill' (Notting Hill), 'To Doubt A Boy (About A Boy) and 'Enough, Actually' (Love, Actually).

In some episodes, the events mirror the film that inspired the episode, such as in 'Ignore Sunrise', Jess and Felix stay up all night in the vein of Before Sunrise.

Then in 'Pink Valentine', aka Michelle Williams and Ryan Gosling's tragic love story Blue Valentine, the episode is focused on the dissolution of Jess and Zev's relationship.

A love letter to Jane Austen.

The series makes several mentions of Jane Austen's famous works. In one of the very first scenes, Jess heals her broken heart by moving in with her grandma (Rhea Perlman), mum (Rita Wilson) and newly separated sister (Dunham) in Long Island.

They spend a Friday night watching Ang Lee's Sense and Sensibility.

"Alan Rickman is so f**king hot," Dunham's Nora offers. "It's one of those faces you look at first, and you're like, 'Hmm.' And then you look for longer and you're like, 'You could get it.'"

Jess also refers to Felix as Mr. Darcy, à la Pride and Prejudice.

Notting Hill.

In Episode 4, Jess and Felix have dinner in Notting Hill. In another scene, Jess forces Felix to snap a photo of her in front of the iconic blue door in the film.

"I'm Julia Roberts, b***h!" she shouts at him as he mocks her.

Bridget Jones' Diary.

In the first episode, Jess walks across the Tower Bridge just like the titular character does in Bridget Jones's Diary.

Then in Episode 6, Jess wears bunny ears in a nod to the movie's tarts and vicars' party. Jess later says she relates to the character, but hilariously refers to the film as 'British Jones Diaries'.

Then there's Jessica's tendency to wear long nightgowns with Felix, another tribute to Jane Austen film adaptations, which echoes Bridget Jones' penchant for rocking unexpected lingerie when romancing a fella.

Never Been Kissed.

Jess rocks up to Felix's friend's fancy British wedding in a tiered metallic-blue mini dress. It's… a lot!

"Are you sure my outfit's OK?" she asks Felix.

The monstrosity was inspired by Drew Barrymore's prom moment in Never Been Kissed.

"[Her dress] was kind of Josie Grossie in Never Been Kissed," Too Much's costume designer, Arielle Cooper-Lethem, told W Magazine.

"It was really important [to show that] she just really didn't get the brief of 'posh English wedding,' and would be easily spotted from anywhere."

Cooper-Lethem even custom-designed the dress for the episode.

There aree loads of other rom-com references.

The whole series is filled to the brim with rom-com callbacks. Jess and Felix endure a chaotic British wedding, referencing Four Weddings and a Funeral.

In one episode, Jess tells Felix's friend she looks like Rachael Leigh Cook in She's All That.

In a flashback scene, Jess imagines herself and Wendy as Grease's Sandy and Rizzo, enjoying a slumber party together.

And the final episode has a deeply unserious Christmas carol performance by Rita Ora which was a callback to Bill Nighy's 'Christmas Is All Around' music video in Love Actually.
