What We Know
Colin Firth was announced as part of the Disclosure Day cast in late 2024. Like much of the film's plot, his specific role has been kept under wraps by Spielberg's notoriously tight production security.
Firth brings both prestige and versatility — equally capable of playing sympathetic authority figures, conflicted antagonists, or morally complex characters caught between duty and conscience.
Fan Theories About His Role

Given the UFO subject matter, Firth might portray a Pentagon official or military leader responding to the events — potentially in conflict with Josh O'Connor's whistleblower character.
