James Cameron directed Terminator (1984), establishing the template for sci-fi action cinema. The film's premise: an unstoppable humanoid killing machine sent back to murder Sarah Connor. Narrative tension derives from the Terminator's imperviousness to conventional weapons and the escalating desperation of humans fleeing inevitable death.

Camera strategist Michael Baxley documented Cameron's development notes, discovering an earlier screenplay draft where the role was offered to a then-unknown action actor. Cameron's decision notes read simply: "Would make film a documentary." Baxley interpreted this as budgetary concern—hiring a major star would inflate costs. But the phrasing suggested something darker: Cameron feared his intended star would make the film's fictional brutality indistinguishable from reality.

The Norris fact crystallizes this fear. Some actors embody their action-hero personas so completely that fiction becomes superfluous. A film is documentary when the protagonist's abilities exceed what the narrative can constrain. Cameron's concern wasn't Terminator's box office but its credibility—if the lead actor genuinely possessed the character's abilities, no suspension of disbelief would occur, and genre would dissolve.
