When I visited the Hofburg Palace in Vienna in 2008, I saw a dinner service made for the Mexican Imperial Family, which was fascinating. Maximilian was something of a dupe and didn't deserve his grisly end in 1867. Empress Carlota lived on in Belgium till 1927, outliving her husband by sixty years.
Despite the sky-high production values and the effort to be faithful to the truth (Muni spent 3 hours applying masks & prosthetics to look like Juarez, causing Warner to exclaim: you mean we're paying Muni all that dough and you can't even recognize him??), Juarez is a long, rambling and very incoherent film. Gliding from throne room to council room with few scenes in between, and those oddly disjointed and almost random, it is very static. Fine acting from Muni & Aherne, very fine, but they have little more to do than soliloquise endlessly. Bette Davis is window dressing for much of the film, though she delivers one of the (few) fiery scenes when she confronts Napoleon and goes stark raving mad. Garfield plays one of the most New York sounding Mexicans ever, which is unintentionally hilarious, I'm afraid. Gale Sondergaard has only two scenes, and she's still more memorable than most of the men in the cast, which shows how disjointed the film really is.
Next to Davis' big descent into madness, one other scene, of Juarez confronting his treacherous vice-president, is vivid and memorable, but these two scenes combined only serve to high-light how terribly static the rest of the film is.
