Thank you. I think we agree on this.
I just watched The Ministry of Ungentlemanly Warfare which was based upon Operation Postmaster… well, like Inglorious Bastards was based on some real stuff. 
The real Operation Postmaster was a heroic operation, in which, afaik no one was killed. Hollywood turned it into a blood fest.,
Okay- they start out by Churchill’s Ministers saying they might have to surrender du to the U-Boat war, or remove Winston. Nope. Sure in 1939, Lord Halifax and some others were seriously considering a peace treaty with Germany- but not a surrender.
Next “our heroes” werent pulled out of prisons- they were a team the Small Scale Raiding (SSRF) and the Special Operations Executive (SOE), in January 1942. No, the team did not land at a Spanish held island with a Nazi base on it (The Spanish were neutral- and yes friendly to Germany, but they iirc they never allowed nazi troops to be garrisoned on Spanish territory), nor did 5 guys kill 50 Nazi troops without a scratch.
Then- they get magic involved- the magic silent Sten gun (yes, Sten guns did have a silencer designed later in 1942, but it only made the gun so it couldnt be recognized as gunfire over 200 yards away. Next, their original plan was to sink the U-Boat resupply ship (which was actually an Italian cargo ship) but it “magically” was retrofitted to become “unsinkable” … just like the Titanic, I guess. 
So they steal the ships- which really happened, but by massacring hundreds of soldiers and sailors. Somehow the italian crew of the Duchessa d’Aosta were all armed with Schmeisser submachine guns. And of course the Spanish port had all those Nazi troops.
Incidentally- the operation IRL did grab that ship, and a German tug, and sail them away. However, they never found any U-boat base in West Africa- which made sense as that’s a long way from the Atlantic shipping lines to the UK anyway. The Spanish very properly raised a diplomatic protest. Nor, IRL were the team put )back?) in prison, but many got promotions and medals. Just about all of those IRL heroes died during the war.
Oh, and of course - my pet peeve- smoking- lots and lots of smoking by everyone.
