Factual error: During the scene where Navajas is throwing knives at El Mariachi and then the Bucho gang in the limo, he slides down in front of the car. The license plate simply says "Mexico" under the serial. Actual Mexican plates of the time period in the movie use the official state abbreviation followed by MEX to identify the state of issue. For example, JAL MEX for Jalisco, which is where the JWF685 serial seen on the plate would have been issued.
Desperado (1995)
1 factual error - chronological order
Directed by: Robert Rodriguez
Starring: Antonio Banderas, Steve Buscemi, Salma Hayek, Cheech Marin
Continuity mistake: During the rooftop shootout Banderas reloads his gun (right hand one), than he takes another gun (the one in his belt) with the left hand. After a cut, Banderas reloads his right handed gun again and the left handed gun disappears.
El Mariachi: Bless me, Father, for I have just killed quite a few men.
Trivia: Carlos Gallardo, who played El Mariachi in the prequel to Desperado, El Mariachi (1992), was given a minor role in Desperado as Campa, the mariachi with the two machine-gun guitar cases.
Question: Why does Zamira (Bucho's henchwoman) have no lines of dialogue? Is she mute? Or was it done to make her character enigmatic?
Answer: Having a tough-looking, silent henchman/henchwoman is a pretty common trope in action movies. She's basically there to look tough and mysterious. I wouldn't read into it more than that, especially given how minor the character is. (Minor enough that I had to Google her, because I couldn't even remember her, and I've easily seen this movie a dozen times over the years).
