Jaded, perhaps, by years of toiling in the Public Access field (and having sat through scores of first, foundering efforts by scores of foundering aspiring filmmakers), I was taken completely by surprise by the remarkable Robert Rodriguez's first film. As sure and as "polished" as any feature, EL MARIACHI belies its no-budget roots and stands as a testament to determination- and talent. If you're one of those whose attention span precludes sitting down and actually reading Rodriguez's book REBEL WITHOUT A CREW, I recommend obtaining a DVD featuring his "ten-minute film school." And pay very close attention: There'll be a quiz afterward.
