Billie Eilish attends the 2024 Oscars (Disney/Chris Willard)Maybe Billie Eilish’s video for “What Was I Made For?” was an audition for her feature film debut acting role. In that video, Billie was dressed in a ’50s-style hairdo and outfit, and that’s the style she’s seen wearing in the first photos from the set of the movie The Bell Jar. The Bell Jar is Billie’s first acting role in a feature film; she made her acting debut proper in the 2023 Prime Video movie Swarm. But unlike many first-time actors, Billie has already co-directed a feature film of her own — Billie Eilish – Hit Me Hard and Soft: The Tour (Live), which opened in May.
