NBC vets Jenna Fischer (The Office), Rob Lowe (The West Wing, Parks and Recreation) and Megan Mullally (Will & Grace) are all returning to the network to star in Apocalypse, a new dramedy about mankind's final days.

The trio, alongside British actor Mathew Baynton, will play extended family members who come together upon news that a comet is on track to hit Earth.

“This is an out-of-the-box and wholly original project that offers just the right combination of both high drama and humor,” NBC Entertainment president Jennifer Salke said of the 10-episode series in a statement. "With a stellar cast ... who know how to expertly balance those lines, we’re ready to dive into the Apocalypse.”

Mullally has been recurring with husband Nick Offerman on Parks and Recreation, while Lowe is also expected to return during the show's final season.
