In "A Sleepless Night", Charley Bowers created the puppet-animation mouse characters that he also used in the very enjoyable feature "Wild Oysters". This feature is not as wildly creative as the later one, but it's still pretty good. Part of the film footage seems to be lost, as well as the audio, which makes it a little harder to evaluate, although it is still not difficult to follow the action.
The mouse family's little home inside the wall has the same endearing detail as it had in the original feature. The action here is not quite as entertaining, but it still does make good use of the imaginative furnishings in the settings.
Bowers's best features set a very high standard, and so it is probably unfair to expect everything he does to come up to the same level. In itself, "A Sleepless Night" is certainly good enough to be worth watching.
