Rose Reid on whether she could play the violin: "I would definitely not call myself proficient, at least not to the extent that Finley is by far. I played 'Twinkle, Twinkle Little Star', and that was it," she says with a laugh. "But we spent three months, countless hours every other day with a violin coach and kind of worked our way up to being able to play the songs that you see me playing on screen."
Inspired by the book "There You'll Find Me" by Jenny B. Jones.
The character of Emma (Saoirse-Monica Jackson) was named Erin in the original source-material book by Jenny B. Jones. If the writers had kept that name, it would have been the same name as Saoirse-Monica Jackson's character in "Derry Girls."
