The movie "Won’t Back Down" has already accomplished the impossible: Making teachers’ unions demand strict accuracy in films about classroom education. For decades, Hollywood has been making movies that show teachers as superhuman caring machines without a peep from the unions. That math teacher played by Edward James Olmos in "Stand and Deliver," the one who took over a classroom of kids who couldn’t do simple arithmetic and in nine months had them aceing calculus exams? History does not record a single union official complaining that, in real life, that process took several years.
