Daisy Edgar-Jones says it's 'bonkers' that Taylor Swift's recorded a song for her new film.
'Carolina' has been written for 'Where The Crawdads Sing' - an adaptation of the book, by Delia Owens.
It's co-produced by Reese Witherspoon - something else the actress described as a 'big moment' for her.
The movie's out later this month.
