Stories from the set

More than one and a half kilometers of trenches were dug for the filming of the movie.

It took 6 months to rehearse all the scenes before filming began.

In the Low Force area, on the River Tees, Teesdale, where the film was shot, signs were put up warning people that the body parts scattered around the site were dummies.

The film was shot in long takes (up to eight and a half minutes), then edited to look like a single continuous take.

Conservationists, concerned that filming on Salisbury Plain near Stonehenge could damage hypothetical burial sites, asked for archaeological surveys to be carried out before any construction began.
