UPDATED: Matthew Weiner has a new series in the works.

Variety has learned exclusively from sources that the “Mad Men” creator is developing a half-hour series at FX. Plot details are being kept under wraps, but the series is being described as a mystery dramedy. Weiner is writing the series and will also executive produce and direct. FX Productions will produce.

FX declined to comment.

Should it move forward, the show would mark Weiner’s return to the world of basic cable, though it could potentially end up on FX on Hulu as well. “Mad Men” aired on AMC for seven seasons, with Weiner having served as director, executive producer, and showrunner in addition to creating it. The show received 116 Emmy nominations throughout its run, including four wins for best drama series.

Most recently, Weiner created the Amazon anthology series “The Romanoffs.” Weiner’s other credits include shows like “The Sopranos” and “Becker,” as well as the feature “Are You Here.”

This project is also the first to be announced for Weiner since he was accused of sexual harassment by “Mad Men” writer Kater Gordon in 2017. Gordon alleges while working together late one night in 2008, Weiner said she owed it to him to let him see her naked. Weiner said at the time that he did not remember making the statement. Marti Noxon, who worked as a consulting producer and writer “Mad Men,” said that she witnessed the aftermath of Weiner’s alleged encounter with Gordon, sharing her account in a series of tweets.

FX’s current lineup includes a number of dramedies, including shows like “Atlanta,” “Better Things,” “Fargo,” and “Mr. Inbetween.” FX’s sister channel, FXX, airs popular comedies like “Archer” and “It’s Always Sunny in Philadelphia” as well as recent entry “Dave,” starring Dave Burd, a.k.a the rapper Lil Dicky.
