box office success despite its limited production costs and started an industry trend, inspiring other comedies such as Porky's, the Police Academy films, the American Pie films, Up the Academy (made by rival humor magazine MAD), and Old School among others. Belushi became the most successful male comedy star in the world until his 1982 death; Bacon also became a star, and he, Matheson, and Allen are among those who have had lengthy acting careers. Reitman, Landis, and Ramis became successful filmmakers; Landis' use of dramatic actors and soundtrack to make the comedy believable became the traditional approach for film comedies.
