The Last Man on Earth...Grows?

The new show I'm most looking forward to this year is the post-apocalyptic comedy on FOX starring Will Forte called The Last Man on Earth. But apparently, the title may be misleading. What was originally supposed to be a one-man show has expanded the cast. January Jones, Kristen Schaal, and Mary Steenburgen have each joined the cast of the highly-innovative show. I suppose it didn't say The Last Human on Earth so the door is open for women to be in the cast. No word yet if they will appear in flashbacks, though. Still excited for more Forte! There's never enough Forte!
