Robert Rodriguez' silly Mexican live-action Mexican cartoon fantasy Desperado (1995)
is supposed to be a sequel to El Mariachi (1992)
but while it is more of a remake of the first movie than anything else, the two are completely independent of one another. Plus, the first movie didn't have Salma Hayek's nude scene, which is really the only reason to watch Desperado (1995)
in the first place.
