Joseph McGinty Nichol, known professionally as McG, is an American director, producer, and former record producer.

Terminator Salvation is a 2009 American military science fiction action film that is the fourth installment of the Terminator franchise, serving as sequel to Terminator 3: Rise of the Machines (2003), but also as a soft reboot. It is directed by McG and written by John Brancato and Michael Ferris. It is the only Terminator film to date not to feature Arnold Schwarzenegger, though his likeness briefly appears digitally. Instead, it stars Christian Bale and Sam Worthington with Anton Yelchin, Moon Bloodgood, Bryce Dallas Howard, Common, Michael Ironside, and Helena Bonham Carter in supporting roles. In a departure from the previous installments, Salvation is a post-apocalyptic film set in the year 2018. It focuses on the war between Skynet's machine network and humanity, as the remnants of the world's militaries have united to form the Resistance to fight against Skynet. Bale portrays John Connor, a Resistance fighter and central character, while Worthington portrays cyborg Marcus Wright. Yelchin plays a young Kyle Reese, a character first introduced in The Terminator (1984), and the film depicts the origins of the T-800 Terminator. After troubled pre-production, with the Halcyon Company acquiring the rights from Andrew G. Vajna and Mario Kassar, and several writers working on the screenplay, filming began in May 2008 in New Mexico, and ran for 77 days.
