New Terminator Salvation trailer is live; watch it here

Update: The trailer is now live at Yahoo! Movies and here. Watch it after the jump.

This is the trailer that debuted at WonderCon in San Francisco over the weekend and will be unveiled on Entertainment Weekly/The Insider tonight.

The trailer opens with Christian Bale's voice-over, with the by-now familiar image of him shooting a Terminator robot head stuck under the tread of a helicopter. A title card flashes with the date 2018; we find out that machines now outnumber humans.

There are quick shots of hundreds of humans trapped in holding pens. John Connor speaks into a radio: "If you can hear this, you are the Resistance." A succession of quick cuts of the motorcycle terminators giving chase, speeding along a road, a shot of the gigantic Harvester plucking humans out of the wreckage of a 7-Eleven. Connor's voice refers to replicating human tissue.

Kate Connor (Bryce Dallas Howard) and John confront a chained Marcus Wright (Sam Worthington). "You think you're human," John says. "I am human," Marcus says. Marcus looks down, sees his exposed chest and screams.

More quick cuts: the helicopter crash, a hunter-killer blowing up a bridge, Kate and John kissing, a collapsing building. Connor stands in a lake, training a pistol on Marcus. Marcus, his face half ruined, exposing what appears to be metal underneath, tells John: "I'm the only hope you have." Then the trailer cuts to an overhead shot of a city, two explosions forming the eyes of a cyborg face. Terminator Salvation opens May 21.
