The Last Man on Earth is getting some company.

Mad Men‘s January Jones and 30 Rock‘s Kristen Schaal have landed significant roles in Fox’s forthcoming comedy, which stars Saturday Night Live vet Will Forte as humanity’s last hope.

Also joining the cast of the single-camera comedy are Mel Rodriguez (Enlisted) and Aussie actress Cleopatra Coleman (Step Up Revolution).

A Fox spokesperson declined to comment on the castings.

Given Last Man‘s premise, it’s unclear how the quartet will figure into the show, although we’re told that portions of the story will be told in flashback.

Character descriptions were not made available, but character names were. Jones, in her first major comedic gig, will play Melissa, while Bob’s Burgers vet Schaal will portray Carol Pilbasian. Rodriguez and Coleman round out the cast as Todd and Erica, respectively.

Forte created the series and will serve as an EP alongside The Lego Movie‘s Phil Lord and Chris Miller, and Drunk History‘s Seth Cohen.

Last Man bows with two back-to-back episodes on Sunday, March 1 at 9/8c.
