Men Must Fight is a 1933 American pre-Code drama film starring Diana Wynyard, Lewis Stone and Phillips Holmes.

[3][4] Nurse Laura Mattson and World War I military pilot Lt. Geoffrey Aiken fall in love after only knowing each other for a few days.

Edward manages to disperse the crowd by first reminding the mob of each American's right to voice his or her own opinion in peacetime, and pledging himself wholeheartedly to the struggle once war is declared.

When Eurasia launches an air raid on New York City, destroying such landmarks as the Empire State Building and the Brooklyn Bridge, hundreds are killed and Laura is injured, though not seriously.

Bob changes his stance and enlists, not in the chemical division as a trained chemist as Edward had suggested, but as an aviator like his real father.

[4] In reviewing Men Must Fight, Mordaunt Hall, the film critic of The New York Times, praised the performances of two of the leads, writing that "Miss Wynyard gives an affecting and very earnest interpretation of a mother who protests vociferously against war ... Mr. Stone does splendidly in his part", while "Phillips Holmes is not especially effective".

[3] In a later review, Leonard Maltin noted the prophetic nature of the plotline, "This powder keg of a film is fascinating on many levels, particularly as it looks into the 'future' and uncannily depicts the world at war and the mainstream popularity of television.
