The 29-year-old actress, who plays Meg March in the film, opened up about the project to Variety, and explained that although the movie is based on Louisa May Alcott's 1868 novel, the narrative is still relevant today.
Suggesting the character Jo March, played by Saoirse Ronan, also struggles to own the copyrights to her written work - just like the "ME!" singer, Emma said: "It's about believing in yourself and knowing your worth and owning your worth."
"Right now, the Taylor Swift situation is a great example of, you know, you're young and you're talented and someone wants to buy your work, but having ownership at the end of the day is super, super important because you don't know what someone's going to decide to do with that."
Taylor has been locked in a feud with record executive Scooter Braun since he acquired her old record label, Big Machine, and with it the masters to the "Shake It Off" singer's first six albums.
The 30-year-old is planning to re-record her first six albums next year (20) when her existing contract with Big Machine's bosses allows her to.
