From NetFlix:

Writer-director Robert Rodriguez’s indie debut and his big-budget follow-up are both featured on this disc. Sundance Film Festival winner El Mariachi chronicles the travails of a traveling musician (Carlos Gallardo) who’s been mistaken for an assassin who carries his weapons in a guitar case — and whom the local crime lord wants dead. In Desperado, the mariachi (Antonio Banderas) returns — this time seeking revenge. Salma Hayek co-stars.

Robert Rodriguez made this film in Mexico for $9000 which is,
of course, absurdly low. He could shoot each scene only once.
For a beginner in Spanish, this is the perfect film because the
Spanish is terse and very easy. This is a violent film.
