Continuity mistake: When the body of Glyndwr Michael (Major Martin) is found by fishermen near Huelva, the sun is setting in the west, almost touching the horizon. The shot of the cart wheeling the body towards the town is filmed, judging by the shadows, at about 3 or 4 in the afternoon. (01:17:57 - 01:18:53)

Operation Mincemeat (2021)
1 continuity mistake - chronological order
Factual error: When Fleming salutes Cholmondeley and Montague, they return the compliment whilst not wearing their headdress. Members of the British armed forces never salute if they are not wearing a hat, instead they would stand to attention.
Question: Is the Spanish flag seen on the building in Huelva the accurate one used during Franco's regime or the modern one?





Answer: During Franco's reign, 1938 to 1977, the flag (Rojigualda) had a different coat of arms, the Eagle of St. John, with 'Una Libre Grande' inscribed. It changed in 1945 to a bigger eagle, overall covering some of the red bands of the flag, so, as this is 1943, from what one can see, the flag is correct in the film.
