Teen comedies weren’t quite a thing yet when Fast Times at Ridgemont High hit theaters in 1982. Porky’s had been a big hit the year before, but Bob Clark’s puerile approach was very different from Amy Heckerling’s more nuanced one even if a lot of critics couldn’t tell the difference. The dawn of John Hughes’s teen comedies that would define the decade was still a couple of years away, and his glossier, more mannered, more melodramatic approach was very different from Heckerling and screenwriter Cameron Crowe’s inclination toward realism.
