Producer Michael Balcon was interested in telling a story about the British prisoner of war experience as his wife, Aileen, was a Red Cross nurse who had dealt with repatriating POWs at the end of the war.
The film's original title was "Lover's Meeting" but novelist Eleanor Smith intervened with the threat of litigation as she had already published a novel with that title. The two properties couldn't be more different but as Smith was on her deathbed, producer Michael Balcon felt obligated to come up with a new title.
The 2016 digital restoration was funded by StudioCanal in collaboration with the British Film Institute's "Unlocking Film Heritage" digitalization program, which is part funded by the UK's National Lottery.
The Marlag und Milag Nord prisoner of war camp, where the film is set and much of it was filmed, was located in the north of Germany, about 30 kms from Bremen. After the German surrender, it was used to house German prisoners of war and then later female refugees. In the 1960s it was a base for a Luftwaffe division of the German army but today it is a business park.
