Each protagonist embodies a different relationship to the unsolved. Toschi represents institutional fatigue: procedure without result. Avery embodies cynical burnout. Graysmith—initially a naive outsider—becomes the film’s tragic center. His transformation from observing cartoonist to haunted investigator is rendered through Gyllenhaal’s performance: increasingly unkempt, isolated, staring at documents until 3 a.m.

Crucially, the film highlights mediation: ciphers, letters, typewriters, phone calls, and later computer databases. The Zodiac’s identity exists only through these traces. One sequence shows the San Francisco Chronicle newsroom receiving a letter; the camera tracks the envelope’s journey from mailroom to editor’s desk.
