Is there any film

I remember a 2014 American movie “WALKING WITH ENEMY” which is based on World War II and inspired from a true story. This story follows the heroic lives of world leader and young man through the horrors of World War II. Both men belong from different places one from Hungary and one from Germany but soon trust of both of them on each other lost as the story continues The Regent takes his country from terror of Nazi Germany and communist Russia and during that period he lost many citizens from that one child named as Elek Cohen determined to find his family and save them and in this race he embarks the journey filled with suspense and danger.
