There’s something illuminating about getting a movie from our neighbors across the pond that offers a winking look at American society. The movie takes its title quite literally, scaring off the Columbia lady with a critter who subsequently carries away the animated title sequence. Because the U.S. might be the prototypical lion, but Grand Fenwick is the mouse that roared.

The minuscule duchy of Fenwick — a measly nation if there ever was one — remains stagnated in the medieval ages, economically and otherwise. Their major exports are wine, particularly popular on the West coast, though competition in the form of copycat businesses proves steep competition.

Teetering on the brink of bankruptcy, the Fenwick leaders resolve to declare war on America. It’s really all part of their contingency plan expecting that their quick and inevitable defeat will lead to American rehabilitation and, thus, newfound prosperity for their little principality. They no doubt are well aware of the Marshall Plan and the U.S.’s undying interest in any floundering nation, they can look to capitalize on. Better us swoop in than have the Soviets socialize them, right?

Regardless, all this poppycock and tomfoolery is made even more palatable thanks to the talents of Peter Sellers. He hasn’t reached Clousseau status nor the apex of his stardom in the 1960s, but he would be an international icon soon enough. For now, we get to sit back and witness him in dialogue with himself. First as the Machiavellian prime minister Mountjoy, then the Queen Victoria knockoff, Duchess Gloriana, and finally, the ultimate Sellers hero, Tully Bascomb.

Because it is this meek and unassuming game warden, who is called upon to lead the charge across the sea onto enemy territory. Armed with their bows & arrows, chainmail, and Fenwickian pluck, their force, 20 men strong, sets off. I mention Bascomb as the prototypical Sellers hero because he’s such a small character, and yet since he is lacking in much, it works impeccably well with the utter outrageousness of the comedy blowing up around him.

Before Monty Python and even before Dr. Strangelove, there was The Mouse That Roared, and not simply due to the trio of roles carried by Sellers. Like its future scion, it takes no umbrage about trampling over Medieval iconography in all its antiquity and finding wells of humor therein. It’s also an atomic bomb-conscious comedy. Surely, you could say almost all comedies of the 50s and 60s were informed by this reality — this pervasive fear — but Mouse takes these themes to heart.

For what generally feels like a humble picture, the moving parts are rather extraordinary. Beyond Sellers, we have director Jack Arnold remembered mostly for his Sci-Fi and monster movies of the 1950s. The marriage sounds less outrageous than it is (or maybe it’s just outrageous enough) because this is meant to be a farce. There are no creatures from the black lagoon or incredible shrinking men, but there is some extraterrestrial hysteria.

It plays with all the alarmist tendencies of the age when the Fenwick contingent prey on a passing truck and punctures its tires, leaving the victims thinking the nation’s being invaded by men from outer space. This streak of nuclear age anxiety with a distinct message is more than enough to wedge it into the rest of Arnold’s canon.

But we have yet to mention Jean Seberg. She’s no doubt at her most childish — she’s only 20 or 21 years old, after all — playing the peeved daughter of a famed scientist. It hardly accentuates her talents nor her playful mystique like Breathless or even Bonjour Tristesse, but it is something different. Because it’s her father’s Q Bomb, which could eat an H Bomb for breakfast, that is currently being tested and is accidentally discovered by the Fenwickians.

In a serendipitous act of lunacy, they instantly become the aggressors ready to take advantage of the situation and bring America to its knees by kidnapping some of its most fundamental assets. It’s the kind of goofy, lightweight stuff taking the edge off. Although there’s an agenda, no matter what implications it might have in the nuclear age, The Mouse That Roared is the perfectly tame goofball comedy we expect to see when we visit sitcoms of the 50s and 60s.

The fish out of water commentary about America dries up when the prisoners are carted back across the pond. Tully and his men make a triumphant return only to be met with some chagrin from the hoodwinked cabinet. They’ve mucked things up. Not only have they not surrendered, they’ve gone and taken hostages and ran off with the most dangerous superweapon in the world!

By this stage, the heart of the comedy has mostly dried up too, though there are a few passing gags relating to the hot potato bomb that wheezes and sizzles to the touch just waiting to annihilate mankind. Likewise, Tully finds himself smitten with feisty young Helen in a love affair that could be telegraphed from miles away. Ultimately, it plays the best when its intentions are made clear with the goofball inanity of it all before didacticism and treacly romance are allowed to give their final stamp of approval on the story. For what it’s worth, I’m one Yank who enjoys being invaded in such a manner as this.
