'There's a line that Lucy Gray says: 'I don't sing when I'm told, I sing when I have something to say.' We get to make our voices heard in a way that's meaningful, then you've done your job as a person.' Rachel Zegler grew up watching Katniss Everdeen in 'The Hunger Games' trilogy, but it all came full circle when she got the call offering for her to play the role of Lucy Gray Baird in 'The Ballad of Songbirds and Snakes.' Rachel breaks down her entire process for the film, from going to Poland to shoot the movie, taking on dialect lessons, the unique costumes she got to wear and so much more.
