Silent film footage from World War One has been painstakingly restored for a new documentary by Lord of the Rings director Peter Jackson.
The archive footage has been combined with original interviews with soldiers who fought in the war.
The Oscar-winning director has used ground-breaking methods, including colourising footage from the Imperial War Museum's archives, to make the film "They Shall Not Grow Old".
Jackson previously said:
"I wanted to reach through the fog of time and pull these men into the modern world, so they can regain their humanity once more - rather than be seen only as Charlie Chaplin-type figures in the vintage archive film."
They Shall Not Grow Old is being released in UK cinemas on 16 October to mark 100 years since the end of the conflict.
Below is the latest trailer and information on the new film. (Source ITV News)
