There may have originally been a potential debate in the OP, but it seems to have been resolved in favor of exploring movie concepts.
Off to CS.

You’ve never read Dennis Wheatley, have you? In some of his books, it’s a given that Communism is an invention and tool of Satan.
Menocchio - if you ever bothered to take a holiday outisde of 15th century Italy you might have had a chance to play “Indiana Jones and the fate of Atlantis”, a very successful game made by Lucasarts for the PC. 
The nub of the story was (paraphrasing) “the time of gods is over, men should decide their own fate”. A bit done now and I’m not sure that the story in the game would have translated into a good film (and it’s just as well they didn’t try to convert it to the screen as no game to film conversion has ever been good).
You can play it for free if your renaissance internet connection allows downloads from the 21st century - find it here
Sorry, I just lied - that game is ESA protected so you can’t download it. Still, if you’re interested you could probably find it on ebay for less than the price of the postage.
When Ronald Reagan died, one of his old movies shown on TCM was a Korean War story set in a POW camp (I will go see if I can find the title on IMDB). I was somewhat amused to observe that the film’s producers weren’t satisfied with showing the Communists running the camp merely torturing and brainwashing their prisoners–and some of these torture scenes were extremely unpleasant, especially for a 1950s movie. To top this and show how truly evil Communism really is, those bastards also killed a cute little puppy!
Since seeing this film, I have occasionaly used the phrase “puppy-killing Commies.”
From the title and descriptions of the torture, this looks like the one: Prisoner of War (1954) - IMDb
Indiana Jones And The Stone Of Destiny
England, 1950. Scots Nationalists have stolen the fabled magical Stone Of Scone from Westminster Abbey. The British Government requests archeology professor Henry Jones II, guest lecturer at Oxford University, to recover the stone.
(According to legend the stone will cry out when the rightful king of England sits upon it. Gee, I wonder what the nsurprise twist will be)
This was also the plot of another (non-Indy) computer game, I forget what it was called. God it’s true, there really are no original ideas…
Purely in the interests of being nit-picky, your link indicates that the non-US gross of FRWL was upwards of 75%. FRWL was a British movie, and as I recall the primary bad guys weren’t communists.
As for Indy Jones - how about something to do with Nasser (cold war connection) and the Pyramids - he discovers that the Rosetta stone was a mis-translation - chases some artefact stolen by Napoleon and spirited away to some glamorous Paris location near the Concorde obelisk - culminating in the discovery of the secrets of ancient Babylon lurking beneath the war-torn streets of modern Baghdad.
Didn’t Dan Brown already do this one?
I’ll get my coat…
According to the IMDb, there’s a rumor this project might have Karen Allen in it! 
Actually, the Soviet spy agency SMERSH was the villain organization in several of Fleming’s early Bond novels, but in the film versions changed the villain to the non-state criminal organization SPECTRE. I guess the Commies were losing their luster even then.
The Commies had luster?
I doubt they even had floor wax!
Are you sure about that? In some cases like The Spy Who Loved Me the Soviet Commies were the competition.
Dr No was a Chinese commie, sure, in the first James Bond, and the commies were also the enemy in For Your Eyes Only, but quite often - as in From Russia With Love (the second movie), You Only Live Twice, Octopussy, and A View to a Kill - it was some other villain (e.g. SPECTRE or Stromberg in The Spy Who Loved Me or Whitaker in The Living Daylights) setting the Soviet Union and the West against each other. In Die Another Day, that the North Koreans were Communist was not mentioned. Looking down the list, I see Dr No (Chinese Commies), Goldfinger (Chinese Commies again), and For Your Eyes Only (Soviets). That’s three out of 21. Hardly ‘quite a few’.
I think the most plausible reason is that there were never any actual Nazis in Hollywood.
You’re not familiar with Mr Gibson then? 
That’s exactly why using the Reds as the villains in an Indiana Jones-type film would not work even half as well as using the Nazis. On a white-to-black scale for good-to-bad guys, the Nazis as a group are solid black whereas the Communists are a dull shade of grey. As foes in fiction, Communists are better suited for more nuanced and ambiguous Cold War thrillers than the Indiana Jones movies which are good vs. evil, white vs. black popcorn flicks.
If I were going to set Indy in 1955. rather than fight the Commies, I’d put him in a central African country fighting for independence against one of the fading colonial powers.
Let’s face it, he’s already been in the Middle East, the Mediterranean, Nepal and (I guess) the Amazon, so he’s running out of exotic locales.
Brain Glutton points to the James Bond movies as examples of cinematic anti-communism… but he couldn’t be more wrong.
Oh, to be sure, Ian Fleming’s books were anti-Red propaganda. And in Fleming’s books, the bad guys were invariably communist agents of SMERSH (supposedly an assassination wing of the KGB).
But in the movies? Nah! The bad guys in the movies were always corporate executives and megalomaniacal businessmen, often members of SPECTRE 9a cvartel of evil international tycoons).
If anything, the Russians were usually portrayed as innocents being framed by SPECTRE, or as plain old good guys.
Now that is what I am talking about. How (now that we know all we know) say the Commies were just ‘grey?’ Lots of individual Russians or Chinese were some shade of grey or course, but as a movement (or whatever) they were as black as night. Is there any doubt as to that now?
(Time to move back to GD?)
