Will Forte on 'Last Man on Earth,' Quitting 'SNL' and Getting Fired From 'Letterman'

Will Forte is riding high these days on the success of his hit comedy series.

Forte added, "Once we came up with the idea, the actual arc of the season came out. But that was just a very general broad strokes document, maybe 10 pages long. But most of it we stuck to."

Being fired changed his thinking.

"The Last Man on Earth" has been renewed for a third season.
