When Does "OPERATION MINCEMEAT" (2022) Take Place?
"OPERATION MINCEMEAT" (released to French-speaking audiences as "LA RUSE") is a historical fiction spy film written by Michelle Ashford that released April 15th, 2022. So when is "OPERATION MINCEMEAT" set?
It takes place in the years:
We know this because the real-world British military intelligence officer Lieutenant Commander (and later spy novelist) Ian Fleming (1908-1964) appears (though he is not directly involved in the real-world events depicted, he is within the fictional world [diegesis] of this film) and he passed on August 12th, 1964 AD. So it has to be before or during August of 1964 AD.

1942 AD - 1943 AD
We know this because the real-world British military intelligence officer Lieutenant Commander (and later spy novelist) Ian Fleming (1908-1964) appears (though he is not directly involved in the real-world events depicted, he is within the fictional world [diegesis] of this film) and he passed on August 12th, 1964 AD. So it has to be before or during August of 1964 AD.
More specifically, the real-world British military intelligence officer Lieutenant Charles Cholmondeley (1917-1982) also appears as an adult character and he was born on January 27th, 1917 AD. So it must be around or after 1937 AD.
1,917 + 20 = 1,937.
Specifically, the narrative depicts Cholmondeley (and Fleming) first suggesting the real-world British misinformation operation code-named Operation Mincemeat to superiors. This happened in the real world in October of 1942 AD.
Furthermore, the July 1943 AD prologue ends with a simple white on black title card reading "Six months earlier ..." So presumably it is January of 1943 AD.
7.1,943 - 6 months = 1.1,943.
Later, the plot shows the military's execution of the plan (part of the real-world global conflict World War II), which occurred in April and May of 1943 AD.
Additionally, the tale includes a prologue in which the joint force of British and American soldiers invade Sicily, Italy and this happened in the real world on July 9th, 1943 AD. So it's July of 1943 AD.
Furthermore, the very first shot of the prologue is a white on black time setting title card that reads: "July 10th, 1943."
