Terminator Salvation is an upcoming American science fiction post-apocalyptic war film set for release on May 21, 2009. Directed by McG, it is the fourth Terminator film and stars Christian Bale as John Connor and Sam Worthington as the Terminator Marcus Wright. It also introduces a young version of the first film's hero, Kyle Reese, played by Anton Yelchin, and depicts the origins of the 800 Series Model 101 Terminator, played by Roland Kickinger. The film, set in 2018, focuses on the war between humanity and Skynet. It abandons the formula of previous entries in the series, which involved Terminators and various other characters traveling through time to kill or protect John Connor.
Set in post-apocalyptic 2018, John Connor (Christian Bale), the man fated to be the leader of the human resistance against Skynet and its army of Terminators, and the future he was raised to believe in is altered in part by the appearance of Marcus Wright (Sam Worthington), a stranger whose last memory is of being on death row. John must decide whether Marcus has been sent from the future or rescued from the past. As Skynet prepares its final onslaught, John and Marcus both embark on an odyssey that takes them into the heart of Skynet's operations, where they find out a terrible secret that may lead to the possible annihilation of mankind.
At the beginning, John does not start off as leader of the human resistance, but will work his way through the ranks in the film. He is mistrusted by other soldiers due to his extensive knowledge of Skynet. McG said that the film will reveal the development of the Model 101 Terminator as well: scenes involve humans being captured and studied by Skynet in order to perfect their cybernetic organisms and John explaining "[i]f we let these things go online, the war is over". Skynet captures Kyle Reese because it is aware that Reese is John's father, and uses him as a bait in an attempt to kill John.
