A short title built around a precise span of time invites close attention to duration. Does an hour pass through visible action, an edit, an ellipsis or a character's account? That is a useful way into 23 Hours: notice what the film chooses to show and what it leaves between scenes. The distinction matters especially when a compact production has to create momentum through decisions and withheld information rather than spectacle. Keep the title's measure in mind without assuming every scene must behave like a literal ticking clock.
