Offering up violent, action-filled tales of mistaken identity and revenge, this double feature includes writer-director Robert Rodriguez's 1992 indie debut, Sundance Film Festival winner El Mariachi, and its big-budget follow-up, Desperado. El Mariachi chronicles the travails of a traveling musician (Carlos Gallardo) who's been mistaken for an assassin. In Desperado, the mariachi (Antonio Banderas) returns -- this time seeking retribution.
