<strong>"Fast Times at Ridgemont High" </strong>Directed by Amy Heckerling and written by Cameron Crowe, this 1982 high school dramedy starring Jennifer Jason Leigh, Phoebe Cates and a young Sean Penn is so realistic because Crowe did his homework -- literally. "I never graduated traditionally, so the idea was that I could go back and have the senior year that I didn't have and write about it what it is to be a high school student," Crowe says in "The Movies." "I learned so much. ... These kids are having a super-short adolescence. It's fast food, it's fast adolescence; it's all disposable." <strong>Where to watch:</strong> Amazon Prime Video (rent/buy); iTunes (rent/buy); Google Play (rent/buy)
