Anthony Hopkins shines as Sir Nicholas "Nicky" Winton in new film One Life.
Winton's unsung endeavours of the eve of World War II saved more than 600 children from their doom at the hands of the Nazis.
He considered himself a banker, not a humanitarian. Yet when he visited Prague in 1938 he saw the state of the fleeing Jewish refugees and did what he believed was the right thing to do - and dedicated himself to the cause. War was approaching and it was a race against time to liberate children before time ran out.
Fifty years later he is haunted by the fate of the children he was unable to help. When he's surprised by the survivors on live television he comes to accept that when facing atrocities, saving even one life is a victory - and the British public learn the truth about the hero hidden in their midst.
One Life, in cinemas from December 26, also stars Johnny Flynn and Helena Bonham Carter.
