Saturday Night Live debuted in 1975, and the show is ready to celebrate with a 40th Anniversary Special this Sunday night. In honor of the occasion, Rolling Stone compiled a mega-list of all the aspiring actors, comedians, and entertainers that were SNL cast members over the years. Some stayed with the show a long time (Kenan Thompson), others did a short stint and became better known for something else (Paul Shaffer, Julia Louis-Dreyfus), and some just faded away. Some became movie stars (Robert Downey, Jr.) and others became TV stars (Jane Curtin, Amy Poehler, Tina Fey). One became a senator (Al Franken), and several died way too early (John Belushi, Phil Hartman). You can skip through to the top twenty, but the top twelve will not surprise you. Scroll through the entire list and you’ll be reminded of Saturday Night Live cast members you’d completely forgotten were on the show.
