Gillian Anderson is receiving major attention at the Cannes Film Festival for her role in Jane Schoenbrun’s film “Teenage Sex and Death at Camp Miasma.” Across coverage, Anderson’s performance is described as striking and unconventional, with reporters and the director highlighting its intensity and impact. She plays a reclusive actress in the movie, which blends elements of a slasher with dreamlike, chaotic storytelling and commentary related to fandom and identity.

One report notes that Anderson’s turn is met with extended audience applause, including a reported six-minute standing ovation at Cannes. Another outlet describes Anderson reacting to the film itself, saying she nearly faints after watching herself on screen.

The film also stars Hannah Einbinder, known for “Hacks,” who plays a young queer filmmaker opposite Anderson. Both outlets frame the project as one of the more unusual entries in the festival’s lineup, combining genre play with themes tied to selfhood and fan culture.
