Jane Fonda and Lily Tomlin will star in a new Netflix comedy called Grace and Frankie.

The Hollywood veterans head the cast of the show as long-time rivals brought together by a rather unusual change in their marital circumstances.

The first season will premiere next year on Netflix. The single-camera comedy focuses on enemies Grace (Fonda) and Frankie (Tomlin), who are facing the last chapter of their lives, though not in the way they might have expected.

When their husbands announce they are in love with each other and plan to get married, the women find their lives both turned upside down and - to their collective dismay - permanently intertwined.

“Jane Fonda and Lily Tomlin are among the funniest and most formidable actresses ever and it’s an incredible privilege to give them the opportunity to run riot on Netflix,” said Ted Sarandos, Netflix Chief Content Officer.

“The show created for them by Marta and Howard is warm, very funny and anything but wholesome. We can’t wait.”
