“Sunrise on the Reaping,” which is based on the 2025 novel of the same name, is set 24 years before the first “Hunger Games” movie. Because it centers on a young Haymitch, most fans assumed that Harrelson would not be involved with the film.

Lionsgate announced it would be producing a film adaptation of Suzanne Collins' "Sunrise on the Reaping" before the book was even released.

Billy Ray, the Oscar-nominated screenwriter of "Hunger Games" and AMC's iconic Nicole Kidman ad, has been tapped to write "Sunrise on the Reaping."
