Most of the big, action-oriented Underground films and the more serious Occupation essays came in 1942-43, so in mid-1941, only a few months after the U.S. was officially in the war, Underground was very much a forerunner of its genre. Too, early in the war, it was comforting in a propagandistic sense, to feel that there was a lively and efficient resistance movement working within Germany itself, even though this was not later substantiated in fact. Thus it was not only a hard-hitting film, but seemed an important one. Like all of the Warner films of the period, it is stylishly done, particularly in matters of photography and art direction; the scenario does manage to keep abreast of those rapidly changing times, and while it is perhaps too heavy a film to be considered an "entertainment" today, its craftsmanship and its cast combine to make it a holding and absorbing film still.
