After eight years on the air at Saturday Night Live, Jason Sudeikis says he's calling it quits.

Sudeikis, who is engaged to actress House Olivia Wilde, used another US late-night TV institution to make his announcement, telling host David Letterman in the taping of Wednesday's show that he's leaving NBC's weekend program. Sudeikis had a busy election year on Saturday Night Live, portraying both Republican Mitt Romney and Vice President Joe Biden.

Sudeikis told Letterman his time on the show has been "really, really amazing".

It's an exodus of male cast members at SNL. Both Fred Armisen and Bill Hader previously announced they were leaving the show. Seth Meyers will be replacing SNL alum Jimmy Fallon on his late-night talk show when Fallon moves up to the Tonight show.
