Not a bad little film, especially if you have never seen the original, but it lacks the atmosphere of the black and white film. Some very obvious goofs are the lack of blackout precautions, the SS Cabinet Minister abandoned but all lit up, and someone from the Ministry of Defence when it was the War Office. Seeing that it's mid War. I'm slightly puzzled at the reference to the Duke and Duchess of Windsor and secret letters. Seems a bit of a red herring.I enjoyed it ,though, No bad language ,a few laughs along the way
