Sarah Jessica Parker wants a divorce.

Not in real life, to husband Matthew Broderick, but on HBO's new dramedy, "Divorce."

The actress posted the first teaser trailer for the series on Instagram. She plays Frances, a woman who wants to split from her husband (Thomas Haden Church) after he has an emotional affair.

Church doesn't think he did anything wrong, and doesn't want to separate, but Parker thinks it's for the best. "Now we can go back to just liking each other again," she says.

The pilot was written by Sharon Horgan, the co-creator and star of Amazon's "Catastrophe." The series also stars Molly Shannon, Talia Balsam, and Tracy Letts, and is slated to premiere on HBO this fall.

HBO is looking to reboot itself after the failure of "Vinyl," which was canceled earlier today, and the loss of dramedies "Togetherness" and "Looking." Bringing in one of its biggest early stars from one of its biggest early hits could do the trick.
