Chaplin's film, aimed obviously and scornfully at Hitler himself, could only have been funny, he says in his autobiography, if he had not yet known the full extent of the Nazi evil. As it was, the film's mockery of Hitler got it banned in Spain, Italy, and neutral Ireland. But in America and elsewhere, it played with an impact that, today, may be hard to imagine. There had never been any fictional character as universally beloved as the Little Tramp, and although Chaplin was technically not playing the Tramp in The Great Dictator, he looked just like him, this time not in a comic fable but a political satire.
The plot is one of those concoctions that makes the action barely possible. The hero, a barber-soldier in World War I, saves the life of a German pilot named Schultz and flies him to safety, all the time not even knowing he was the enemy. Their crash landing gives the barber amnesia, and for twenty years he doesn't know who he is. Then he recovers and returns to his barber shop in the country of Tomania (say it aloud), only to discover that the dictator Hynkel has come to power, not under the swastika, but under the double cross. His storm troopers are moving through the ghetto, smashing windows and rounding up Jews (the term "concentration camp" is used early, matter-of-factly). But the barber's shop is spared by the intervention of Schultz, now an assistant minister, who recognizes him.
The barber (never named, just like the Tramp) is in love with the maid Hannah (Paulette Goddard, Chaplin's estranged wife at the time). And he is befriended by his former neighbors. But he and the disloyal Schultz are eventually put in a concentration camp, and then Hynkel has a boating mishap, is mistaken for the barber, and locked into the camp just as the barber and Schultz escape-with Hynkel's uniform. Now the barber is assumed by everyone to be the dictator.
In the classic Chaplin tradition, the movie has a richness of gags and comic pantomime, including Hynkel's famous ballet with an inflated balloon that makes the globe his plaything. There is a sequence where five men bite into puddings after being told the one who finds a coin must give his life to assassinate Hynkel. None of them want to find the coin and there is cheating, but eventually-see for yourself. And there is a long, funny episode when the dictator of neighboring Bacteria, Benzini Napaloni (Jack Oakie), pays a state visit. Napaloni, obviously modeled on Mussolini, eludes an attempt to make him sit in a low chair so the short Hynkel can loom over him. And when the two of them sit in adjacent barber chairs, they take turns pumping their chairs higher than the other. There is also a lot of confusion about saluting, and Chaplin intercuts shots of the two dictators with newsreels of enormous, cheering crowds.
In 1940, this would have played as very highly charged, because Chaplin was launching his comic persona against Hitler in an attempt, largely successful, to ridicule him as a clown. Audiences reacted strongly to the film's humor; it won five Oscar nominations, for picture, actor, supporting actor (Oakie), screenplay, and music (Meredith Willson). But audiences at the time, and ever since, have felt that the film comes to a dead end when the barber, impersonating Hynkel, delivers a monologue of more than three minutes that represents Chaplin's own views.
Incredibly, no one tries to stop the fake Hynkel. Chaplin talks straight into the camera, in his own voice, with no comic touches and only three cutaways, as the barber is presumably heard on radio all over the world. What he says is true enough, but it deflates the comedy and ends the picture as a lecture, followed by a shot of Goddard outlined against the sky, joyously facing the Hynkel-free future, as the music swells. It didn't work then, and it doesn't work now. It is fatal when Chaplin drops his comic persona, abruptly changes the tone of the film, and leaves us wondering how long he is going to talk (a question that should never arise during a comedy). The movie plays like a comedy followed by an editorial.
Chaplin (1889-1977) nevertheless was determined to keep the speech; it might have been his reason for making the film. He put the Little Tramp and $1.5 million of his own money on the line to ridicule Hitler (and was instrumental in directing more millions to Jewish refugee centers). He made his statement, it found a large audience, and in the stretches leading up to the final speech, he shows his innate comic genius. It is a funny film, which we expect from Chaplin, and a brave one. He never played a little man with a mustache again.
