I saw the site being prepared for the World War 1 battle scenes - amazing - some est 10 acres of land worked over into trenches, barbed wire and all the rest. It was just outside Guildford by the A3 and M25, Elm Corner, and there is an old airfield in there.
Nearby residents all got some not inconsiderable recompensation for the night scenes (though many of them stayed to watch) and the dust - they flattened everything afterwards but the dust coming off in wind was horrendous...
