You could not have made a phone call from England to Paris during war time.

When Rose Winters is seen taking tea with Captain Mainwaring some of the crockery is of the Royal Albert design 'Old Country Roses'. This pattern of crockery is regularly seen in British TV programmes set more than 50 years ago but in actual fact was not introduced until 1962.

When Rose is discovered on the beach with a spy radio, the radio is described as "a crystal set" which she's using to transmit intelligence back to the Nazis. It's impossible to transmit from a crystal set as it has no source of power so they can only ever receive signals which also have to be fairly strong and local. It's a popular belief that all vintage radios are crystal sets whereas this term describes a very particular and primitive type of radio receiver.

A U-boat would not be able to operate submerged so close inshore; indeed it's so near to the beach that it's astonishing it didn't run aground even on the surface.

Walmington-on-Sea is shown to be approximately half way between Brighton and Eastbourne. A Home Guard platoon from that location would not be chosen to patrol a base near Dover, over 75 miles away. Home Guard units did not venture out of their own districts.

At Walmington station, which is established as being on England's south coast, varnished teak London and North Eastern Railway (LNER) passenger cars can be seen on the track in the background. The Southern Railway was the main operator in that part of England in 1944, and the LNER never operated south of London. However when the "Big Four" railway companies came under wartime government control, they sometimes had to share rolling stock, so it is not totally implausible that LNER carriages were seen in Southern territory.

When Rose is on the beach and discovered with the radio set by Vera she pulls out a silver Luger pistol. Whilst not impossible it would not make a great deal of sense to send an undercover agent to an allied country and give them such a blatant giveaway of their true identity, especially if it was discovered. For this reason not all German spies were armed and those that were would have carried something far smaller, more discrete and easier to hide. Small calibre weapons such as those made by Walther would have been far more appropriate. In fact Rose may even have been given a small confiscated American piece such as a Derringer, which would have been easier to conceal and easier to explain away if it had been discovered.

The exterior shots of the place where Rose Winters is staying are stills as the waves in the background are not moving.

No-one on board the submarine manned or fired any of the submarine's weapons during the fight on the beach. Surely the crew of the submarine would have supplied covering fire for the German landing party.

The clock on the wall in the bank has the minute hand showing 'twenty minutes to' but the hour hand is about 'ten minutes past' nine.

When Rose Winters & Daphne are alone in the mouth of the cave, you can see army boot foot prints in the sand..

In the 'camouflage' scene, the troops are standing in a field containing a cereal crop sown with a modern seed drill, complete with 'tramlines', not achievable until the early 1980s.

In the opening scene when the spy lights his roll-your-own the match box strike is a modern polka-dot type, not the dark grey solid strike used prior to the mid-70s.

About an hour into the film, Pike opens the door to his girlfriend at night and speaks to her for about a minute with the hall light on. I was expecting Hodges to arrive and shout 'Put that light out!', but he didn't so obviously an oversight, a blatant one, on the crew's part.

Rose is wearing stockings without a seam, but seamless stockings were not available until well after the War.
