The worldwide trailer for Dawn of the Planet of the Apes has been released ahead of the film's debut this winter.
Matt Reeves is directing the sequel - a follow-up to the 2011 Planet of the Apes reboot, Rise of the Planet of the Apes.
The storyline does not pick up immediately after Rise, which saw the end of humanity's reign on earth after apes took over in the wake of a devastating virus. Instead, it continues a decade later.
The new clip opens with a bleak scene showing the apes trekking through a forest on horseback. A gruff, ominous chant of "Apes, together, strong" can be heard, before the first humans arrive on the scene.
