As early as 1935, producer
Hal B. Wallis had proposed a film about
Maximilian I of Mexico and
Benito Juárez to director
Max Reinhardt. At the time, he was interested in casting
Luther Adler as the titular Mexican president. In 1937, Wallis and
Jack L. Warner, in an effort to dissuade any other studios from embarking upon a similar project, purchased the screen rights to both the novel
The Phantom Crown by
Bertita Harding and the play
Juarez and Maximilian by
Franz Werfel, and on September 30,
Aeneas MacKenzie began writing a first draft under associate producer
Henry Blanke's supervision. According to Blanke, "Our problem from the outset in preparing this story for the screen was by no means one of glossing over facts, but rather one of cleaving to the exact line." To ensure the film was as accurate as possible,
Warner Bros. head of research Herman Lissauer acquired three hundred books on the subject, and two historians were hired to help with changes to the script. The epic film boasted 1,186 supporting players performing on 54 sets designed by art director
Anton Grot and his assistant
Leo Kuter. The largest was an 11-acre replica of Mexico constructed on a ranch in
Calabasas, California. Behind the throne room and living quarters of Maximilian (
Brian Aherne) was a 250-foot-long and 50-foot-high backdrop of Mexico City, with
Popocatépetl in the distance.
Erich Wolfgang Korngold researched the music popular in Mexico during the period and discovered it was "unmistakenly Viennese." He composed 3,000 bars of music for the score, at times emulating the rhythms of
Frédéric Chopin and
Franz Schubert, and the second theme of the first movement of his
Violin Concerto was drawn from his work for the film. Audience reaction to the first preview was so negative the film was recut, with entire scenes transposed. A new ending designed to soften Muni's portrayal of Juárez was filmed, although the scene - in which Juárez visits the cathedral where Maximilian is lying in state and asks for his forgiveness - has no basis in fact. The film opened in
New York City on April 24, 1939, and went into general release on June 4. ==Critical reception==
