The most obvious possible misconception some fans might have about The Ballad Of Songbirds And Snakes is that the story she tells serves as the origin for the entire Hunger Games narrative. However, this is not the case.
Neither the Civil War that resulted in the Capitol viciously dominating the districts nor the first Hunger Games feature in history. The book is set when President Snow – then just Coriolanus Snow – is a teenager (portrayed in the adaptation by Tom Blyth) climbing the political ladder. A major event in it is the 10th official Hunger Games, where Snow mentores Lucy Gray Baird (Rachel Zegler), a District 12 tribute. For chronological reference, at the first Hunger Games, Katniss Everdeen (Jennifer Lawrence) accepted the 74th edition of the deadly competition. If math still works the same in a YA dystopia, it means The Balad of Songbirds and Snakes, set 64 years before the events of the first franchise installment.
While fans should expect the film to crank up the action, The Ballad Of Songbirds And Snakes is not inherently the same type of story as the original trilogy (or tetralogy in the case of the cinematic adaptations). Snow is mostly an observer. An actively sneaky, deadly, terrifying observer, but an observer nonetheless. Another, simpler way of putting it is this: Expect more political intrigue and less battle-hardened reality stars.
