Sam Worthington has recently signed on to star in McG's Terminator Salvation: The Future Begins. According to Variety, James Cameron wisely recommended to McG that he should look towards Worthington for the lead role.

Worthington will play the role of Marcus, a central figure in a three-picture arc that begins after Skynet has destroyed much of humanity in a nuclear holocaust. A group of survivors led by John Connor (Christian Bale) struggles to keep the machines from finishing the job.
