New trailer for Terminator: Genisys includes huge twist: SPOILERS

An action-packed new trailer has landed online for Terminator: Genisys.

Featuring a load of footage we've not seen before, it reveals a lot more about the film's plot, as well as a key twist about John Connor (Jason Clarke), who may not be all that he seems.

We also get peeks at what look like some of the film's central action set-pieces, including a Golden Gate Bridge scrap that should bring the house down.

Check out the trailer below...

Terminator: Genisys opens in UK cinemas on 3 July 2015.
