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 ambiguitythis NOT knowingis 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 ambiguousthe 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 toas 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.

By the numbers story of the Kid (Prince), a singer, on his way to becoming a star. Then he falls in love with Apollonia (Appolonia Kotero). But he has to deal with his wife-beating father (Clarence Williams III!) and his own self-destructive behavior.
I saw this in a theatre in 1984. I was no big fan of Prince but I did like the three big songs from this movie--"Purple Rain", "Let's Get Crazy", and "When Doves Cry". The concert scenes in this movie are great--full of energy and excitement. Unfortunately that's a VERY small portion of the movie.
The story is screamingly obvious and have been done many times before--and much better too. The subplots are, to put in nicely, badly handled. The love triangle between The Kid, Appolonia and Morris Day was so predictable and tired that I actually became insulted. His wife beating father is needed for the story, but the scenes are so badly handled (in acting and direction) that I couldn't believe it. The script is terrible--lousy dialogue and some truly painful "comedy" routines. And there's tons of misogyny here--The Kid's mother getting beaten; The Kid hitting Appolonia and (for no reason) Appolonia strips and goes topless to swim in a dirty river. Also Williams' and Princes' characters treat women in a horrible manner constantly.
The acting is where this movie REALLY fails. Appolonia is sweet and beautiful--but no actor. And Prince is (easily) the WORST actor I've ever seen. His blank face and wooden dialogue delivery are so bad I couldn't believe it. This movie only comes to life during the concert scenes but there aren't really that many. The "dramatic" scenes are so badly acted and handled that they make this movie a chore to sit through. They should have just made this a concert film. I give this a 2--only for the music.
