Lillian Hellman, one of America's most famous women playwrights, was a woman with a mission. Her leftist views were not well regarded at the time in the country. In her memoir, she recounts her trip to the then, Soviet Union, as she was intrigued with the so called successes achieved by that system. "Watch on the Rhine" must have come as a result of those years. The left wing in America, as all over the world had an issue with the rise of fascism, not only in Europe, but in Japan as well.
"Watch on the Rhine" was a play produced on Broadway eight months before the Pearl Harbor attack by the Japanese. In it Ms. Hellman was heralding America's entrance in World War II. The adaptation is credited to Ms. Hellman and Dashiell Hammett, her long time companion. As directed for the screen by Herman Shumlin, the film was well received when it premiered in 1943.
We are introduced to the Muller family, when the film opens. They are crossing the border to the United States from Mexico. They are to continue toward Mrs. Muller's home in Washington, D.C., where her mother, Fanny Farrelly, is a minor celebrity hostess. The Mullers, we realize are fleeing Europe because of the persecution there against the opponents of the advancing totalitarian regime in Germany. In fact, we thought, in a way, the Mullers could have been better justified if they were Jewish, fleeing from a sure extermination.
We find out that Mr. Muller has had a terrible time in his native land, as well as in other places because his outspokenness in denouncing Fascim. Little does he know that he is coming to his mother-in-law's house that is housing one of the worst exponents of that philosophy.
The film offers excellent acting all around. It is a curiosity piece because of Bette Davis' supporting role. Paul Lukas, repeating his Broadway role, is quite convincing as Kurt Muller, the upright man that wants to make a better world for himself and his family. Mr. Lukas does a great job portraying Kurt Muller, repeating the role that made him a stage luminary on Broadway.
The other best performance is by Lucile Watson, who plays Fanny Farrelly, the matriarch of this family. Geraldine Fitzgerald is seen as Marthe de Brancovis, a guest of the Farrellys, married to the contemptible Teck de Brancovis, a Nazi sympathizer, played by George Coulouris. Beulah Bondi, Donald Woods, and the rest of the supporting cast give good performances guided by Mr. Shumlin.
The film should serve as a reminder about the evils of totalitarian rule, no matter where.

I can't believe I waste my time watching this garbage! I did because Leonard Maltin gave it an "AA" rating, and for TV movies this is usually a reliable indicator of some quality entertainment.
The acting was OK, but whoever wrote it should be forever denied access to any medium of communication. The plot is ludicrous, the motivations of the "bad guys" totally absent, and the various family interactions silly and shallow. For example, Dad preaches that violent reaction to aggression is BAD, but he turns out to be an "admirable" person NOT because of his "ignore the idiots" philosophy, but because he's pretty good with his fists...
The ONLY message I was able to glean from this pap was that the nuclear family is Good and alternate living arrangements are Bad. Oh, and Bad people happen to Good people.
