13 Best Sydney Sweeney Roles That Made Her a Star

Sydney Sweeney has quickly become one of Hollywood’s most talked-about young actresses, and for good reason. From small-town dramas to big-budget blockbusters, she has shown an incredible ability to transform into wildly different characters.

Her performances have earned award nominations, millions of fans, and a reputation for taking on roles that are bold, emotional, and unforgettable. Here is a look at the 13 roles that truly put Sydney Sweeney on the map.

1. Everything Sucks! (2018) — Emaline Addario

Before the world knew her name, Sydney Sweeney was stealing scenes in this charming Netflix coming-of-age series set in 1996 Oregon.

As Emaline Addario, she played the cool, drama-club queen who was equal parts magnetic and complicated.

Emaline was the kind of character who seemed to have everything figured out on the outside but was quietly searching for who she really was.

Sweeney brought a surprising emotional depth to the role that made viewers genuinely root for her.

For a young actress still finding her footing in Hollywood, this performance was a clear signal that big things were coming.

2. The Handmaid’s Tale (2018–2019) — Eden Spencer

Playing Eden Spencer in Hulu’s dystopian drama was a turning point that showed Sweeney could hold her own in heavyweight television.

Eden was a deeply religious, naive young girl forced into a world she barely understood.

What made the performance remarkable was how Sweeney conveyed innocence and quiet tragedy without a single wasted moment on screen.

The character’s arc was heartbreaking, and Sweeney handled it with a maturity far beyond her years.

Critics took serious notice, and fans quickly realized this was not just another pretty face — this was a genuinely gifted performer worth watching closely.

3. Sharp Objects (2018) — Alice

HBO’s Sharp Objects was one of the most critically praised miniseries of 2018, and even in a small supporting role, Sweeney made a lasting impression.

Alice was a fragile, haunted girl living in a psychiatric facility alongside the show’s lead character.

The role did not give her much screen time, but Sweeney used every second wisely.

Her quiet intensity and ability to communicate pain through subtle expressions were immediately striking.

Sharing scenes with seasoned veterans like Amy Adams, Sweeney held her ground confidently.

It was the kind of role that quietly builds a career without anyone fully realizing it at the time.

4. Once Upon a Time in Hollywood (2019) — Snake

Getting cast in a Quentin Tarantino film is a big deal no matter how large or small the role, and Sweeney made the most of her moment in this Oscar-winning masterpiece.

She played Snake, a member of the Manson Family commune hanging around the Spahn Ranch.

The character was eerie, sun-soaked, and quietly unsettling — perfectly in tune with the film’s tense late-60s atmosphere.

Sweeney’s natural screen presence ensured she was noticed even among a star-studded ensemble.

Getting to work alongside Leonardo DiCaprio and Brad Pitt early in her career gave her confidence and credibility that money simply cannot buy.

5. Euphoria (2019– ) — Cassie Howard

Cassie Howard is arguably the role that made Sydney Sweeney a household name, and it is not hard to understand why.

On HBO’s Euphoria, Cassie is a beautiful, emotionally volatile teenager desperately seeking love and validation in all the wrong places.

Sweeney poured everything into this character — the ugly crying scenes, the obsessive behavior, and the moments of genuine vulnerability became some of the most discussed scenes in modern television.

She earned Emmy nominations for this role, and the internet practically broke every time a new Cassie scene dropped.

This character proved that Sweeney was not just talented — she was a full-on star.

6. The White Lotus (2021) — Olivia Mossbacher

Mike White’s razor-sharp satire The White Lotus gave Sweeney one of her most layered and entertaining roles to date.

Olivia Mossbacher was a privileged, philosophy-quoting college student who weaponized wokeness while being completely self-absorbed.

The character was funny, uncomfortable, and oddly relatable all at once — a tricky balance that Sweeney pulled off with effortless precision.

Her chemistry with co-star Brittany O’Grady added a wickedly entertaining dynamic to every scene they shared.

The show became a cultural phenomenon, and Sweeney’s Emmy nomination for Outstanding Supporting Actress in a Limited Series confirmed that her performance was one of the season’s very best.

7. The Voyeurs (2021) — Pippa

Amazon Prime’s thriller The Voyeurs handed Sweeney her first true leading role in a feature film, and she grabbed the opportunity without hesitation.

As Pippa, she played a young woman who becomes dangerously obsessed with watching her neighbors across the street.

The film explored themes of desire, morality, and consequence in ways that kept audiences genuinely guessing until the very end.

Sweeney carried nearly every scene with a grounded, believable performance that far exceeded what the genre typically demands.

It was proof that she could anchor a film on her own — a skill that would serve her very well in the years ahead.

8. Nocturne (2020) — Juliet Lowe

Released as part of Amazon’s Welcome to the Blumhouse anthology, Nocturne gave Sweeney a chance to explore something genuinely dark and psychological.

She played Juliet Lowe, a gifted but overlooked pianist who discovers a mysterious notebook belonging to a student who died under suspicious circumstances.

Watching Juliet’s transformation from shy underdog to something far more dangerous was both thrilling and deeply unsettling.

Sweeney leaned fully into the character’s obsessive hunger for recognition, making every scene feel tightly wound and unpredictable.

For fans who only knew her from lighter roles, Nocturne was a revelation that showed just how wide her acting range truly stretched.

9. Reality (2023) — Reality Winner

Based on an actual FBI transcript, Reality is one of the most unusual and impressive films in Sweeney’s entire catalog.

She played Reality Winner, a real-life former intelligence contractor who leaked classified documents about Russian election interference and was arrested in her own home.

The entire film takes place in real time during the interrogation, which meant Sweeney had to sustain incredible tension for nearly the whole movie.

She delivered a performance so grounded and precise that it felt more like a documentary than a drama.

Film critics praised it as her finest dramatic work, and many viewers came away genuinely moved by Winner’s story.

10. Anyone But You (2023) — Bea

Nobody expected Anyone But You to become one of the biggest romantic comedies in years, but Sydney Sweeney and Glen Powell had other plans.

As Bea, Sweeney played a sharp, funny, and fiercely independent woman who reluctantly pretends to date her nemesis at a destination wedding in Australia.

The film was pure, delightful fun — and Sweeney’s comedic timing turned out to be every bit as sharp as her dramatic instincts.

Her chemistry with Powell was electric and completely convincing, making audiences genuinely root for the couple despite knowing exactly where things were headed.

The film grossed over $215 million worldwide and proved Sweeney was a full-blown box-office draw.

11. Madame Web (2024) — Julia Cornwall

Taking on a superhero role is always a gamble, and Madame Web was a film that received mixed reviews from critics upon release.

Still, Sweeney’s portrayal of Julia Cornwall — one of three young women connected to the mysterious Madame Web — showed her willingness to step boldly into blockbuster territory.

She brought energy and likability to a role that did not give her a tremendous amount to work with story-wise.

Fans appreciated seeing her in a completely different setting than her usual dramatic fare.

Whatever the film’s overall reception, Sweeney’s star power was undeniable, and her presence alone drew millions of viewers to theaters worldwide.

12. Immaculate (2024) — Cecilia

Sweeney did not just star in Immaculate — she produced it, which says everything about how personally invested she was in bringing this story to life.

She played Cecilia, an American novitiate nun who travels to an isolated Italian convent and discovers something deeply sinister lurking beneath its holy walls.

The film leaned hard into gothic horror territory, and Sweeney committed completely to every terrifying, physically demanding scene.

Her final sequence became instantly iconic among horror fans and was widely shared across social media.

Immaculate proved that Sweeney had both the creative vision and the raw courage to lead a genuinely scary, boundary-pushing horror film.

13. Big Time Adolescence (2019) — Holly

Sandwiched between bigger projects, Big Time Adolescence was a quietly charming indie film that deserved far more attention than it received.

Sweeney played Holly, the girlfriend of Pete Davidson’s slacker character, and brought a grounded warmth to a role that could have easily been forgettable.

Holly was not a flashy part, but Sweeney made her feel real — funny, a little exasperated, and genuinely caring in a way that added heart to the whole film.

Her natural chemistry with Davidson made their scenes feel lived-in and authentic.

Small roles like Holly are often where the best actors quietly sharpen their craft, and Sweeney was no exception.
