On Sunday, February 15 Saturday Night Live will have been making its audience laugh and smile for 40 years. For 40 years we have seen the stage Lorne Michaels created birth many a legends like Eddie Murphy and Chevy Chase to the more modern Amy Poehler and Tina Fey. To celebrate SNL's success and 40-year air time the show is planning a three-hour primetime special for the 15th that features a reunion of former cast members, hosts, and musical guests. It is an all-star lineup of sorts as Chris Rock, Tina Fey, Kanye West, Justin TImberlake, Maya Rudolph, Peyton Manning, Derek Jeter, Tom Hanks, Amy Poehler, and many more are slated to appear. Below we have provided two promos for SNL's 40th anniversary special that reveals more of the reunion cast. Be sure to tune in Sunday, February 15 at 8pm on NBC.
