“Wonder Woman” screenwriter Allan Heinberg has signed on to work with famed executive producer Shonda Rhimes for a dramedy pilot on ABC.

According to TV Line, the pilot, tentatively titled “Adult Behavior,” is described by the network as a sexy, multi-generational comedy drama. The new show is based on the British gay comedy series, “Cucumber and Banana.” Logo TV also release episodes of “Cucumber and Banana” in the United States in 2015.

Rhimes and “Grey’s Anatomy” executive producer Betsy Beers will assume similar roles in “Adult Behavior.” “Cucumber and Banana” creator Russell T. Davies will also be working closely with Rhimes and Beers.

Meanwhile, this is not the first time that Rhimes will be working with Heinberg. The latter has been a longtime member of the Shondaland family, serving as executive producer and co-executive producer on “Grey’s Anatomy,” “Scandal” and “The Catch.” His other TV credits include “The O.C.,” “Sex and the City” and “Gilmore Girls.”

Other than talking about the highly-successful “Wonder Woman” film, Heinberg also talked about the cancellation of “The Catch” last month. While speaking with Entertainment Weekly, the exec confirmed that he and his team already had ideas for Season 3. However, none of these storylines will be explored since ABC decided to axe the series after two seasons due to low ratings.

“Getting Ben and Rhys back together is going to take a number of episodes in Season 3, and their relationship is never going to be the same. When we meet Rhys in Season 3, he’s in an even more different power dynamic; he’s even more powerful than he was at the end of Season 2. It’s not going to be easy to take Rhys down by any means… Of course, going into Season 3, all Rhys wants to do is make everything okay with Ben and Alice,” he explained.

Additionally, Heinberg said that Margot’s (Sonya Walger) and Ben’s (Peter Krause) daughter, Tessa (Philippa Coulthard), would’ve been given more storylines in Season 3. The character was introduced towards the latter part of Season 2, and she became instrumental in helping her parents and Alice (Mireille Enos) complete their missions.

“The Catch” Season 2 aired its final episode on May 11.
