Terminator Salvation is an upcoming American science fiction post-apocalyptic war film set for release on June 4, 2009 in Australia, June 3, 2009 in the UK and May 21, 2009 in the United States. Directed by McG, it is the fourth film in the Terminator series and stars Christian Bale as John Connor and Sam Worthington as Marcus Wright, a cyborg who believes he is human. It also introduces a young version of the first film's hero, Kyle Reese, played by Anton Yelchin, and depicts the origins of the T-800 Model 101 Terminator, played by Arnold Schwarzenegger and Roland Kickinger. Being both a sequel and a prequel to the previous films, Salvation, set in 2018, focuses on the war between humanity and Skynet. It abandons the format of previous entries in the series, which only revolved around Terminators and various other characters traveling through time to either kill or protect John Connor before the events of Judgment Day unfold. It is the first film in the series to receive the PG-13 certificate in the USA, and the second to receive a 12A certificate in the UK.
