6. Depending On The Weather

They brought in meteorologists and other weather experts to the set so they could be ready for the light and weather they needed, which, in a gloomy and gritty World War 1 movie, is cloudy.
But when shooting the ending scene they had to wait around for the clouds to disappear and the sun to come around.
