Billie Eilish Makes Acting Debut in Swarm, in a Mysterious Role

Billie Eilish just teased something major, and it’s not a new album — it’s her acting debut. 

Surprise! Billie is set to guest star in Donald Glover’s new Prime Video series Swarm, which premiered at SXSW in Austin, Texas on March 10. Swarm is set between 2016 and 2018 and stars Dominique Fishback as twisted heroine Dre, an obsessive fan of the world’s biggest pop star whose fandom takes a dark turn, sending her on an unexpected cross-country journey. Swarm has already received lots of buzz for its bloody trailer and the seemingly intentional similarities to Beyoncé and her fandom the BeyHive. (Fun fact: Malia Obama is credited as a writer on the series, after discreetly joining the writers room back in March 2022.)

Now, who Billie plays in Swarm is a bit unclear. Her mysterious character, named “Eva” according to IMDB, is being kept a bit under wraps, and her part has already been rumored to be a dangerous, demented therapist or the leader of an all-female cult.

In the teaser the musician posted to Instagram on March 16, we see a blonde Billie opposite Dominique as Dre, asking her what she sees and looking very pleased when Dre admits that she hurt someone. “Very good,” Billie’s character says in a low, haunting voice. Um, I have chills?
