Lorne Michaels, who created “Saturday Night Live” and has overseen its creative trajectory since the show’s 1975 debut, confirmed that he plans to stay at the show beyond its upcoming 50th season — a milestone he previously said would be his swan song. “[SNL is] always going to be described the same way, which is ‘uneven,’ and yet people have decided somehow that it’s important,” Michaels said in a new Hollywood Reporter interview. “And so as long as it’s important and I can be useful, I’ll stay.”
