There's many reasons I could give for why Robert Rodriguez is such a cult figure among movie nerds, but here's the biggest: his first movie was El Mariachi. El Mariachi was an action film he managed to shoot on a pithy 7,000 dollar budget that turned out to be pretty damn good, thus helping jumpstart the concept of independent film. He later followed it up with the larger-scale Desperado and Once Upon A Time In Mexico, and now he may be working on a fourth.
There's not much more information on how it would happen, as the director has only stated that:We forgot about how much fun we've had together," Rodriguez said. "We decided we have to do something. We want to do another EL MARIACHI movie at some point. We always said we would, but [we'd shoot it] much later when he's (Antonio Banderas) older and rounder... We have to figure something else out, because he's in better shape now than he ever was.
The films tell the story of a wandering, unnamed guitar player, played at first by Carlos Gallardo and then by Antonio Banderas who carries around a guitar-case full of guns. None of the El Mariachi films were ever good enough to be classics, but they were all a ton of fun for the audience and really showed a great deal of personality. That, and the action scenes were always awesome, so we should welcome a fourth one.
