When the Marichi is singing 'Ganas de vivir' in the bar to a full house, Domino is at the bar watching him perform. We then see a customer snap his fingers at her to get her attention, and to get a drink. When she serves him, we see him for the first time. According to the commentary, he is the actual owner of the bar.

Director Robert Rodriquez spent a month in a clinic as a "test dummy" to earn the money to film the movie. They only had enough film for one shot. Any of the mistakes found are due to the limited budget available, as they couldn't afford to correct themselves.

At the time of filming, Carlos Gallardo, who plays the Mariachi, actually lived on the same street where much of the chase scenes took place.
