Jason Sudeikis Confirms He's Leaving 'Saturday Night Live' On 'Letterman'

It's been rumored for months now, but Jason Sudeikis finally confirmed that he will not be returning for the upcoming season of "Saturday Night Live" after 10 years with the show.

The 37-year-old comedian made the announcement while appearing on last night's "Late Night" with David Letterman, saying "I'm definitely done."

Sudeikis, who worked as a writer for two years on the show before appearing on camera for eight, wants to start focusing on his film career. And his sex life with fiancé Olivia Wilde.

"It's not weird now," he admitted of leaving the NBC sketch comedy show, "but you start to get that itch in August when all these sketch ideas will show up and I'll be like, 'Can I make this sketch last 90 minutes and turn it into a movie?'"
