Now in its 39th season, Saturday Night Live is a cultural pillar on par with 60 Minutes and Monday Night Football. Under Lorne Michaels' four decades of stewardship, the show has always introduced new talent — but this year featured a bigger shift than most. With heavy hitters like Fred Armisen and Bill Hader leaving, SNL added six new faces while asking existing staffers like Taran Killam to step to the forefront. A cast member since 2010, Killam has become known for characters like critic Jebidiah Atkinson (not to mention his video spoof of Robyn's "Call Your Girlfriend" video). On the eve of SNL's annual holiday episode, we sat down with him to discuss the legacy of digital shorts, his new comic book side project The Illegitimates, and how SNL continues to be an important cultural voice.
