"The Russians are Coming" is a dated comedy not because of its subject matter, but because of a 1960s comedic style that, for whatever reason, some found amusing then but is now painful to watch. At least for me.
This film has been compared to "It's a Mad, Mad, etc. World" and it is an appropriate comparison. If you found that film funny you will no doubt find this amusing as well. For myself, it takes more than an all start cast hamming it up before a camera and extras running around in the background to make me laugh. I require some cleverness or unpredictability to the shtick. Unfortunately, this film has neither.
For example, from the moment Ben Blue (Luther) is not able to immediately corral the horse he needs in order to warn the town that "the Russians are coming," was there any doubt that the camera would continue to check in on him from time to time, as he tries to capture the horse in drab, unfunny ways? Or that the film would end with him riding through the town long after the Russians left?
What amazes me is that you can watch comedies from the silent era that can blow you away with the inventiveness and creativity of the stunts and situations. A movie like "The Russians are Coming" doesn't even give it half an effort. Instead, this is what is supposed to pass for "hilarious" according to reviewers here: townspeople running around while Jonathan Winters with a grimace admonishes "Let's get organized!" And if you found that hilarious, you're in for a treat, because evidently the director found it so funny the bit just HAD to be repeated!
Don't get me wrong, I like Carl Reiner, Alan Arkin, Paul Ford, Jonathan Winters, even Brian Keith in some things when the material is good. For instance, Paul Ford in "The Music Man" was funny. Here, doing the same kind of character, but without any funny lines, he is just outright annoying.
To make matters worse, the bits which are not funny to begin with are dragged out in order to stretch this film out to over 2 hours. Example: toward the end of the film, Sheriff Brian Keith tells the Russian sub commander he is under arrest. This "joke" is dragged out for what seems like fifteen minutes, long past the time when it could be amusing to anyone.
How anyone can describe this as "hilarious" is beyond me. Maybe those who have do not know what the word means. Here is the definition, just in case:
Hilarious: marked by or causing boisterous merriment or convulsive laughter.
This film may force you to convulse something, but for myself it was absolutely not laughter.
