While promoting his new flick We're the Millers on The Late Show, the Bad Bosses star confirmed the rumors that have been floating around all summer about his exit.
"I'm definitely done," he told David Letterman. "I'm gonna leave. I'm not coming back next fall."
He also told the late-night host that right now, he doesn't feel weird about not coming back to SNL, but next month might be a different story.
"You'll start to get that itch probably in August where all these sketch ideas will show up and I'll be like, 'Well, can I make this sketch idea last 90 minutes and turn it into a movie?!' Probably not," he jokes. As long as you make it more like the original Wayne's World and less like It's Pat, we'll be all right.
And there is no bad blood here between the show and Sudeikis, who calls his experience on the sketch series "fantastic."
"It's been really, really amazing. I was very, very lucky," he says.
"You never really leave that place, and it never leaves you," he said, "It's an emotional journey getting through a season, much less the final one."
