Terminator Salvation

About the film

Contains story spoilers.

Terminator Salvation shifts the series into the human-machine war after Judgment Day. Its prologue begins in 2003, when death-row prisoner Marcus Wright agrees to donate his body to Dr. Serena Kogan’s research after his execution. The story then moves to 2018, where John Connor leads an attack on a Skynet facility and finds evidence that captured humans are being used in the development of a new Terminator. A nuclear blast destroys the base, and John survives. Marcus awakens in the wreckage, confused and heading toward Los Angeles, while the Resistance prepares for an assault on Skynet’s headquarters in San Francisco. The wrecked facility contains captured people and machinery in different stages of construction, giving John evidence that the war is changing shape.

John learns that Skynet has compiled a kill list naming him and Kyle Reese, a young survivor John knows will travel into the past and become his father. Marcus meets Kyle and a mute child named Star in Los Angeles. When machines attack, he cannot prevent the two children from being captured. After Resistance aircraft are shot down while trying to intercept the transport, he rescues pilot Blair Williams and travels with her toward John’s base. A magnetic mine wounds Marcus on arrival, and the Resistance discovers that his body contains a metal endoskeleton and an artificial portion of his brain. He insists that he is still human, but John and his wife Kate believe Skynet may have sent him to infiltrate them. Kyle’s capture makes that uncertainty urgent: preserving him matters to the Resistance’s future and to the chain of events that allowed John to exist.

Blair helps Marcus escape execution, and John pursues him. During that pursuit, Marcus saves John from Skynet’s aquatic machines. The rescue changes their relationship: John needs access to the machine network, while Marcus wants a chance to survive and understand what has happened to him. They agree that Marcus will help John enter Skynet’s base and rescue the prisoners. Meanwhile, Resistance commanders plan to attack immediately after receiving a signal they believe will disable the machines. John questions that intelligence and asks for time to free Kyle and the others, but General Ashdown removes him from command. John’s plan is not simply to destroy a machine base; he is trying to free the prisoners without making the Resistance’s larger attack even more vulnerable.

The story’s two protagonists approach the war from different directions. John is already a leader whose public authority competes with the Resistance’s chain of command; Marcus is a stranger who cannot be classified as wholly human or machine. John’s radio broadcasts and the commanders’ strategic meetings show a movement trying to coordinate scattered fighters, while Marcus’s journey moves through ruins and machine-controlled territory at ground level. The contrast makes the setting more than a backdrop. The war is fought through information, signals and decisions about who can be trusted, as well as through gunfire and pursuit.

Marcus enters Skynet’s headquarters and disables its perimeter defenses, allowing John to infiltrate the facility. Skynet reveals that it resurrected Marcus to lure John into a trap, and that the supposed shutdown signal is a ruse; the Resistance’s command submarine is destroyed. Marcus tears out the hardware linking him to Skynet and chooses to help John anyway. John reaches Kyle and Star, but a T-800 attacks them. As the children escape, Marcus fights the machine while John rigs explosives from fuel cells. The T-800 stabs John through the chest, and Marcus destroys it by tearing off its head.

McG directs John Brancato and Michael Ferris’s screenplay around two competing forms of knowledge. Christian Bale’s John has grown up with his mother’s account of the future, while Sam Worthington’s Marcus does not even know what his own body has become. Anton Yelchin’s Kyle recognizes John as a voice of resistance without knowing their family connection. The characters therefore do not stand on equal ground when they decide whom to trust. Marcus’s rescue of Blair gives Moon Bloodgood’s pilot a reason to defend him before the others understand him, and Kate’s medical judgment makes the discovery of his machinery harder to dismiss. The final sacrifice answers Skynet’s intended use of him through an act that the network did not choose on his behalf.

John is evacuated with Kyle, Star and Marcus, but doctors say the damage to his heart will kill him. Marcus offers his own human heart for a transplant, sacrificing himself so John can live. The operation succeeds, and John radios the Resistance to say the battle has been won while the war continues. The film’s large machine designs and bleak production landscapes give the battlefield a harsher, industrial scale, while the plot stays focused on whether Marcus’s acts can outweigh the use Skynet made of him. The ending changes the expected hero’s survival through a choice made by the person who began the film as a condemned prisoner.
