Sydney Sweeney can make you laugh in one movie and leave you shaken in the next. Her work ranges from small but striking appearances to leading roles in dramas, comedies, and horror films.
Looking beyond her biggest hits shows just how much she can do. Whether you want a light romance or a tense character study, these performances offer plenty to explore.
1. Cassie Howard in Euphoria
Behind Cassie’s bright smile sits a deep fear of being unwanted. Sweeney makes that need for love feel painfully real, even when Cassie’s choices hurt the people around her.
Her performance earned an Emmy nomination for supporting actress in a drama series.
Watch how her face changes when confidence slips into panic. Those small shifts help explain the character without excusing her behavior.
Expect mature themes, troubled relationships, and scenes that can be emotionally difficult.
2. Olivia Mossbacher in The White Lotus
A raised eyebrow can say plenty, especially when Olivia is judging everyone nearby. On a family vacation in Hawaii, this sharp college student mixes social awareness with a striking lack of kindness.
Sweeney turns that contradiction into uncomfortable comedy.
Her work in the first season earned an Emmy nomination. Pay attention to Olivia’s conversations with her friend Paula, where loyalty and jealousy quietly compete.
Choose this role for biting humor rather than a lovable heroine.
3. Reality Winner in Reality
No grand speech is needed to make this performance gripping. Playing former NSA contractor Reality Winner, Sweeney relies on pauses, careful answers, and nervous movements during an FBI interview.
The film draws its dialogue from the actual recorded encounter.
That approach gives ordinary exchanges an uneasy weight. Notice how her polite manner slowly becomes strained as the situation grows clearer.
This is a strong choice for viewers who prefer quiet tension over action or elaborate twists.
4. Eden Spencer in The Handmaid’s Tale
Few of Sweeney’s characters seem as unprepared for cruelty as Eden. Introduced in the second season, the young bride believes deeply in Gilead’s rules while struggling with feelings those rules cannot safely contain.
Her innocence makes the story especially painful.
Sweeney avoids turning Eden into a simple symbol. Instead, she shows a teenager seeking affection and certainty in a frightening world.
Watch the series in order for context, and expect disturbing material involving religious control.
5. Snake in Once Upon a Time in Hollywood
Sometimes a brief appearance leaves a surprisingly sharp impression. As Snake, a member of the Manson Family, Sweeney helps make Spahn Ranch feel unsettling before much happens.
Her guarded presence adds to the tension surrounding Brad Pitt’s visit.
Don’t expect a large storyline or much dialogue from her here. The appeal lies in seeing how she contributes to a crowded scene through attitude and expression.
It’s a useful reminder that memorable acting isn’t measured by minutes.
6. Alice in Sharp Objects
Music becomes a small bridge between two people carrying heavy pain. In this dark miniseries, Alice shares a psychiatric facility room with Camille, played by Amy Adams.
Their connection gives Sweeney room to show both teenage warmth and deep distress.
Her scenes are limited, but they help explain Camille’s emotional life. Listen to the pauses as closely as the dialogue.
Viewers sensitive to self-harm or suicide should check content warnings before watching this especially sorrowful role.
7. Emaline Addario in Everything Sucks!
Big feelings and bigger theater energy make Emaline hard to overlook. Set in the 1990s, this Netflix series follows students navigating friendship, filmmaking, and identity.
Sweeney brings swagger to a girl whose confidence doesn’t tell the whole story.
As Emaline’s relationships change, softer feelings begin breaking through her bold front. The show lasted only one season, making it a manageable watch.
Try it when you want an early performance with humor, awkwardness, and genuine teenage longing.
8. Bea in Anyone But You
Trading sharp remarks can be its own kind of flirting. Opposite Glen Powell, Sweeney plays Bea, whose awkward history with Ben becomes a problem at an Australian wedding.
Their solution is to pretend they’re a happy couple.
The setup gives her room for physical comedy, embarrassment, and moments of sincerity. Enjoy the sunny scenery, but watch how she balances irritation with attraction.
For fans used to her darker work, this offers a breezy change of pace.
9. Juliet Lowe in Nocturne
Every wrong note seems to carry a personal insult for Juliet. An ambitious pianist living in her twin sister’s shadow, she becomes drawn to a mysterious notebook that appears to promise success.
Sweeney makes her hunger for recognition feel increasingly dangerous.
The horror grows from familiar worries about talent, comparison, and falling behind. Look at how her posture and gaze change as ambition takes control.
Pick this film if you enjoy psychological unease with an artistic setting.
10. Pippa in The Voyeurs
Looking through the window starts as curiosity and becomes something far riskier. Pippa moves into a Montreal apartment with her boyfriend, then grows absorbed in the private lives of neighbors across the street.
Boundaries quickly begin to disappear.
Sweeney plays the pull between excitement and guilt without making Pippa easy to trust. Avoid plot summaries if you want the surprises intact.
With sexual content and disturbing turns, this thriller suits adults seeking glossy suspense rather than comfort.
11. Cecilia in Immaculate
A peaceful welcome can hide a terrible trap. Arriving at an Italian convent, Cecilia hopes to build a life of faith, only to face events that make her question the people around her.
Sweeney moves from trust to terror with striking force.
She also served as a producer on the film, adding another reason fans may find it interesting. Watch for the growing strength beneath Cecilia’s fear.
Be prepared for graphic violence and disturbing pregnancy-related horror.
12. Christy Martin in Christy
Boxing gloves signal a very different challenge for Sweeney. In this 2025 biographical drama, she portrays Christy Martin, the fighter who helped bring women’s boxing to a wider audience.
The role explores life beyond the ring as well as athletic ambition.
Martin’s story also involves domestic abuse, so expect more than a sports victory tale. Consider watching interviews with the real boxer afterward for added context.
The contrast with Sweeney’s romantic and teenage roles is especially notable.
13. Eva in Night Teeth
Cool confidence replaces nervous energy in this brief vampire outing. Eva belongs to the dangerous nighttime world surrounding a young driver in Los Angeles.
Sweeney shares the screen with Megan Fox, giving their scenes an extra dose of star power.
Her part is small, so approach it as a supporting appearance rather than a leading showcase. The pleasure comes from her sleek, commanding presence.
Save this one for an evening when stylish supernatural action sounds appealing.
14. Scarlett in Downfalls High
Pop-punk songs do much of the storytelling in this unusual screen project. Sweeney plays Scarlett, a popular student whose relationship with an outsider anchors the story.
The film builds its world around Machine Gun Kelly’s album Tickets to My Downfall.
Rather than expecting a traditional musical, settle into its music video style and heightened emotions. Sweeney supplies a human center amid the loud visuals.
It’s a useful pick for fans curious about her work outside standard television and films.
15. Julia Cornwall in Madame Web
Glasses and a shy manner introduce a different kind of comic book character. Sweeney plays Julia Cornwall, one of three young women drawn into Cassandra Webb’s struggle against a deadly threat.
Julia is connected to the comics’ Julia Carpenter, not Madame Web herself.
Keep expectations focused on an origin setup rather than a full superhero showcase. Her scenes lean on uncertainty, teamwork, and glimpses of future possibilities.
Fans following her genre experiments may appreciate this unusual detour.
