For Streep, this film wasn't only about the singing (we all knew she could from Mama Mia!
and Into the Woods
), but it presented her with the challenge of learning the guitar. The film's director, Jonathan Demme, shared with Yahoo Movies
, "Meryl has told me that from the time she was a kid, she at the age of seven found herself in front of a radio loving electric guitar and rock 'n roll. She has lived as this kind-of wannabe guitar beast, and this part gave her the opportunity to actually do that."
