Billie Eilish recalls the moment Greta Gerwig approached her with the 'Barbie' project.

Initial skepticism: Eilish expected 'Barbie' to be 'all fun and pink,' a typical fantasy 

Gerwig's explanation reveals a deeper, emotionally resonant narrative. 

Eilish highlights a moving scene with Barbie at a bus station - a defining moment. 

A speech by America Ferrara and Rhea Perlman's portrayal as Ruth Handler left audiences hushed. 

These heartfelt scenes inspired Eilish's music, adding a soulful layer to 'Barbie’s' story.
