The Fatal Mallet is full of unexplained, unnecessary, and gratuitous 1914 violence, like most of Chaplin's films for Keystone, but at least the plot is very easy to follow because it stays simple and doesn't try to tell more of a story than the technology of the time would allow. It begins with a lot of brick throwing between Chaplin and a man and wife (the wife does most of the throwing), until ultimately Charlie and the man are engaged in a brawl. Meanwhile, the wife finds another man, a huge brute of a man who is unaffected by Charlie and the first husband hitting him on top of the head with bricks. When he fails to notice that anything is happened, the two love scorn men are forced to regroup and come up with a new plan while the new guy makes his affections known to the woman.
The two enemies now working together allows Chaplin to do some of his usual tricks and pranks but to actually have a reason to do them this time, and ultimately it turns into a brawl that is every man for himself, since they are all enemies to begin with. Chaplin's love of falling into the lake and throwing other people into the lake is certainly not forgotten here, but among the films of the time, I think this one stands out as one of the clearer and more entertaining ones, even though so much of it is the same as so many others.
Also of note here is what I think might be the first appearance of a small boy in an important role in one of Chaplin's films. I say important role, however, only to mean that there is a kid in more than a background role. I am not sure if it is more disturbing than amusing, but I would lean toward amusing just because, even though the kid shows up just long enough for Charlie to punt him off screen like a football, he is clearly having a great time and his imitation of Chaplin's backwards fall is uncanny. Certainly not the best, but this is among the better of Chaplin's Keystone comedies.
