Sydney Sweeney is barely in her 20s and yet she’s been an integral part of some of the most noteworthy TV series created in the past few years. Although her first credits appear in 2009, your first recollection of her may be from the unrenewed show Everything Sucks! on Netflix. That same year, Sweeney swept the small screen in poignant roles, such as Eden Spencer in Hulu’s The Handmaid’s Tale and HBO’s Sharp Objects. These projects were quickly followed by her strong and heartbreaking portrayal of Cassie Howard in Euphoria. If you haven’t tuned into The White Lotus, you don’t want to miss her subtle, infuriating, and moving performance.
