A new documentary offers an incisive, open-minded look at the right to roam debate: the ongoing struggle to judge who holds and crosses Britain’s land.

Despite its many country paths and parks, a huge amount of the UK is closed to the public by private ownership – supposedly, over 90% in England. Since the 1930s, activists have fought to open up more of this land to walkers, struggling against landowners with historic claims of guardianship and with harder questions of environmental responsibility. As this issue rages on today, director Orban Wallace interviews figures from across the battle lines, shedding light on the issue with calmness and thoroughness. Alongside it, his radiant vision of the British countryside reminds us of what’s being fought over, while asking: who gets to experience this, and who takes care of it?
