American playwright Howard W. Campbell, Jr. (played with a musty obsolescence by Nick Nolte) lives happily in Germany with his actress wife, Helga Noth (Sheryl Lee) before the beginning of World War II. At the peak of his life, Howard is drafted by an American agent (John Goodman) to become a spy on behalf of the Allies; forewarned of the risks the job holds, Howard has everything to lose, but finds the offer irresistible. Following the death of his wife and the end of the war, Campbell camouflages himself with the anonymity of a solitary life in New York City, which muddies his neuroses even further. The central question (indeed, a question that has frustrated many critics) of the movie and Kurt Vonnegut's source novel is, "is Campbell a hero or a traitor?" Director Keith Gordon and screenwriter Robert B. Weide offer us clues, but no answer, and this ambiguitythis NOT knowingis what keeps "Mother Night" fresh and interesting throughout. At the beginning of the film, Nolte portrays Campbell as intelligent and confident; by the end, he's either scared and uncertain, or scared and COMPLETELY certain of his contribution/debt to humanity for the role he played in the war. Gordon applies a certain icy sheen to the images of the film's first half, which complement his portrait of the Nazi bourgeoisie and captures Vonnegut's dramatic side. On the flip side, when Campbell is confined to his lonely New York apartment (which he affectionately calls "purgatory") only to be discovered by a group of Nazis, the humor produced also is purely distinctive of the author, and provides a temporary respite from the dramatic tension that unfolds. The moral (even spiritual) paradox "Mother Night" presents doesn't lend itself to simple resolution, and to a degree, should be left ambiguousthe black-and-white scenes of Campbell staring wearily into space as he is imprisoned in Israel suggest an unspoken contemplation we are not made privy toas Campbell is a character whose inner workings we wind up knowing very little about; the war changes him, coming back to America changes him, and meeting up with the Nazis in New York compels him to prolong the facade of his "act" even further, to the point where he can only stare wearily at an image of himself projected on a wall, spewing anti-Semitic bile. Perhaps that's the best reaction we could hope for.
Output:
positive
