The film marks the directorial debut of Chief Minister Vijay's son, Jason Sanjay. It is produced by Subaskaran under the Lyca Productions banner. The makers describe it as "a high-stakes heist" film. Recently, writer-director Jason revealed that his directorial venture offers a blend of action, comedy, treasure-hunt, and heist which contribute to a highly energetic cinematic experience.
