Sydney Sweeney (birthname: Sydney Bernice Sweeney) burst into popular consciousness as Cassie in HBO’s acclaimed series, Euphoria (2019-present), but this was following a decade of work laboring in small supporting roles on the big and small screen.
The only two features of note for Sweeney during this early period were, first, a role in John Carpenter’s psychological horror movie, The Ward (2010), starring Amber Heard, Mamie Gummer, Mika Boorem, and Jared Harris; and then, in director/writer/producer David Robert Mitchell’s surrealist noir, Under the Silver Lake (2018), co-starring Andrew Garfield, Riley Keough, and Topher Grace, and which premiered at the Cannes film festival before its domestic release by A24.
Sweeney’s first notable co-starring role was opposite Otmara Marrero in writer-director Lisa Gallagher’s drama, Clementine (2019), earning her good reviews at its Tribeca film festival premiere before release by Oscilloscope. Quentin Tarantino then cast Sweeney as one of the “Manson girls” in his sprawling drama/comedy, Once Upon a Time in Hollywood (2019), while many of Sydney Sweeney’s most significant film roles during this time, marked by the COVID-19 epidemic, landed on streaming, including writer-director Zu Quirke’s horror movie, Nocturne (2020); writer-director Michael Mohan’s thriller, The Voyeurs (2021); the Adam Randall-directed vampire thriller, Night Teeth (2021).
Sweeney’s wave of direct-to-streaming movies ended, however, with an exceptional work and performance premiering at the Berlin Film Festival, and thus, was treated more as a cinema than TV work: director-writer Tina Satter’s chamber drama streamed on Max, Reality (2023), adapted from Satter’s play of the same title drawn from the transcript of the FBI arrest and interrogation of U.S. intelligence leaker, Reality Winter. Sweeney then starred in writer-director Tony Tost’s crime thriller, Americana (2023), with Paul Walter Hauser, Halsey, and Eric Dane, which premiered at the South by Southwest Film Festival.
Starring in her widest release to date, Sweeney played opposite Glen Powell in a contemporary spin on Shakespeare’s Much Ado About Nothing, the Will Gluck-directed rom-com, Anyone but You (2023), with Alexandra Shipp, GaTa, Hadley Robinson, Michelle Hurd, Dermot Mulroney, Bryan Brown, and Rachel Griffiths, and released by Sony Pictures.
Sydney Sweeney joined the Marvel Cinematic/Spider-Man Universe as Julia Carpenter/Spider-Woman in Madame Web (2024), co-written and directed by S.J. Clarkson, and starring Dakota Johnson, Celeste O’Connor, Isabela Merced, and Tahar Rahim. Sweeney’s first feature as producer and co-star was the psychological horror drama, Immaculate (2024), reuniting her with director Michael Mohan and released by Neon.
Sydney Sweeney (replacing Alicia Vikander) joined the ensemble of Ana de Armas, Jude Law, Vanessa Kirby, and Daniel Brühl in director-producer Ron Howard’s Galapagos-set drama, Eden (2024). Sweeney then co-starred with Julianne Moore and Domhnall Gleeson in the Ridley Scott-produced thriller for Apple Original Films, Echo Valley (2025), directed by Michael Pearce.
Sweeney portrayed the lead title character of pro boxer Christy Martin and was also a lead producer in director/co-writer/producer David Michôd’s biopic, Christy (2025), co-starring Ben Foster, Merritt Wever, and Katy O’Brien, premiering at the Toronto Film Festival and produced by Anonymous Content/Yoki Inc./Votiv/Fifty-Fifty Films/Black Bear Pictures. Sweeney starred and was an executive producer of director/producer Paul Feig’s psychological thriller, The Housemaid (2025), based on Freida McFadden’s 2022 novel, co-starring Amanda Seyfried, Brandon Sklenar, and Michele Morrone, and released by Lionsgate.
Sydney Sweeney led the cast of director/producer Paul Feig’s thriller, The Housemaid (2025), adapted from Freida McFadden’s 2022 novel by screenwriter Rebecca Sonnenshine, with Amanda Seyfried and Brandon Sklenar, and released by Lionsgate. Sweeney joined the cast of the long-awaited sequel, The Devil Wears Prada 2 (2026), adapted by Aline Brosh McKenna from Lauren Weisberger’s 2013 sequel novel Revenge Wears Prada: The Devil Returns, reprising the original cast of Meryl Streep, Anne Hathaway, Emily Blunt, Tracie Thoms, Tibor Feldman and Stanley Tucci under David Frankel’s direction, with new cast mates Kenneth Branagh, Lucy Liu, Justin Theroux, B.J. Novak and Lady Gaga, and released by 20th Century Studios.
