Trivia, insights & behind the scenes
Nainika, who plays Vijay's daughter, is the real-life daughter of actress Meena — Atlee cast her after seeing her natural chemistry with Vijay during rehearsals.
Theri cemented Atlee's template: emotional prologue, bouncy middle, devastating flashback reveal, explosive finale — a structure he'd repeat in Mersal and Bigil.
