Sam Worthington will star alongside Christian Bale in Terminator Salvation: The Future Begins.

The Australian actor recently portrayed the lead in the James Cameron-directed Avatar, as that famous director reportedly recommended Worthington to Terminator Salvation director McG.

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 (Bale) struggles to keep the machines from finishing the job.
