More Action Footage From 3 New 'Terminator Salvation' TV Spots

Gearing up to its theatrical release in May, "Terminator Salvation" has teased more of its explosive action through three brand new television spots. Entitled "Join Us", "Join Us II" and "The Human Spirit", all of the spots highlight on John Connor's radio broadcast, asking people who are listening to join the Resistance in their effort to fight the machines.

"Join Us" displays more never-before-seen footage from the action thriller along with John Connor's dialog. It has similar footage with "Join Us II", but the latter one has less dialog and focuses more on the shooting down of a Skynet vehicle. Meanwhile, "The Human Spirit" spot gives out an extended opening from John Connor and new dialog from Kyle Reese.

Set in post-apocalyptic 2018, "Terminator Salvation" is the fourth feature film installment in the "Terminator" franchise. It centers on the time human survivors join John Connor and his resistance army in the battle against the Skynet's killing robots. Amidst the gruesome battle, Marcus Wright, a stranger whose past could not be justified, comes along and joins the army.

While Connor is struggling to decide whether Wright has been sent from the future or rescued from the past, he and Wright uncover the terrible secret behind the possible annihilation of mankind. Starring Christian Bale and Sam Worthington as Connor and Wright respectively, it will also have Moon Bloodgood, Common, Anton Yelchin, Bryce Dallas Howard and Helena Bonham Carter among the cast. The Warner Bros. movie is set for U.S. release on May 21.
