Filming high-stress, sexually charged scenes across multiple seasons demanded rigid professional boundaries. Sweeney has been vocal about the vital presence of intimacy coordinator Amanda Blumenthal, who served as a protective liaison between the young cast and the production crew. The intimacy coordinator choreographed physical positioning down to precise centimeters, implementing modesty garments, barriers, and explicit consent checkpoints before every take.
Sweeney consistently advocated for her own autonomy during production. When Levinson’s scripts included scenes where Cassie was written to appear shirtless without narrative justification, Sweeney directly intervened. On multiple occasions during Season 2 filming, Sweeney told Levinson that nudity was unnecessary for the emotional truth of the scene, and Levinson agreed to revise the blocking.
That balance allowed Sweeney to protect herself while still committing fully to demanding sequences. Whether spending hours submerged in tepid water for the hot tub scene or enduring the emotionally bruising shouting matches opposite Alexa Demie and Jacob Elordi, Sweeney's physical stamina became an essential component of Cassie's tragic screen presence.
