American Pie brought the raunchy teen sex comedy to a whole new generation: Porky's ran so that the Pie franchise could fly. The tale of four friends (Jason Biggs, Chris Klein, Thomas Ian Nicholas, and Eddie Kaye Thomas) determined to lose their virginity before high school graduation was an unexpected hit with similarly minded, gross-out-ready teenagers. The movie catapulted many of its young leads into stardom, and the vast majority of the cast returned for Pie's direct sequels, including American Pie 2, American Wedding, and American Reunion.
