The newest film in The Hunger Games franchise, The Hunger Games: The Ballad of Songbirds and Snakes, has introduced some very interesting backstories for characters that the original trilogy already introduced, including the rebel and President Snow's cousin, Tigris. The Ballad of Songbirds and Snakes is a prequel to The Hunger Games trilogy and follows Coriolanus Snow as he becomes a mentor during the tenth Hunger Games and forms a close relationship with his tribute, District 12's Lucy Gray Baird. The new movie stars Rachel Zegler, Tom Blyth, Hunter Schafer, Peter Dinklage, and Viola Davis. It is based on a book of the same name by Suzanne Collins.
