Tina Fey, whose hit show 30 Rock ran on NBC for three seasons, has landed a new TV series with the network.

The Office's Ellie Kemper is set to star on the new sitcom, about a woman who starts a new life in New York City after escaping from a doomsday cult.

Fey's longtime writing and producing collaborator Robert Carlock, who worked with her on all seven seasons of "30 Rock," which ended in January, is also on board with the project.

“We have been lucky enough to work at NBC for our entire careers (except when Robert worked at The Dana Carvey Show, now available on DVD) and we thank [NBC Entertainment chairman Robert Greenblatt] Bob and Jen [Salke] for their continued support,” Fey and Carlock said via a joint statement.

Fey and Carlock are co-writing and co-producing the as-yet-untitled series.

"Original voices like Tina and Robert don't come along very often and we wanted them back on the air as soon as possible," says NBC Entertainment president Salke. "And to have them working with Ellie Kemper — who we watched grow up on The Office from supporting player to leading actress — puts the whole package together. We feel fortunate to be in business with this entire creative team on something so funny, unique, and attention-getting."

A fall 2014 debut is planned for the new show, for which NBC has ordered 13 episodes.
