This sentimental M-G-M "gangster" film works like a "Tarzan" in reverse: here the seemingly incorrigible hood played by Montgomery, urbane and a touch cynical, finds his cold heart surely melting in the warm embrace of a simple farm family and their soothing workaday life.
In "Tarzan" Maureen O'Sullivan is the "outsider", and although she must adjust to life in the jungle the thrust of that story is that she "domesticates" the "ape man" even as she learns to accept the simpler pleasures of living "close to nature". Here Montgomery is the one out of his element and we find him mystified by the sounds of crickets in the evening--something almost as strange and foreign to him as the unpretentious caring ways of the Miller family. When Mom and Pop and little "don't call me" Willy (played by young Mickey Rooney) conveniently leave the farm for a day, Montgomery and O'Sullivan get to play "farm" (baling the hay, splitting wood) the same way Tarzan and Jane get to play "house" together. In both cases O'Sullivan has "tamed" the wild beast.
"Tarzan" was an adventure film, however--the journey takes place in the great outdoors and nature is a mirror. "Hide-out" is an inner journey, on the other hand--even as he's hauled off to prison Montgomery smiles because he's finally come "home".
