The movie was filmed without a soundtrack. Narration, voice-overs and some sound effects were added in post-production. To avoid having to synchronize the audio to the picture, characters speak only when their faces are either off-screen or not clearly visible due to darkness or distance. Likewise, during scenes in which firearms are used, the muzzles of the guns are usually out of shot when the weapons are fired. During scenes of gunplay, many characters appear at first to have suffered life-threatening bullet wounds, only to appear in later scenes fully recovered with no visible signs of having been wounded. Extensive narration is used in lieu of plot points being conveyed through dialogue. Film historian Bill Warren stated "The AFI catalog says (the film) may have been reissued in 1964 as "Girl Madness""
