“Westworld’s” Bash Doran has been set to executive produce and run “Demimonde” as part of a two-year overall deal, reports TheWrap.

HBO placed a straight-to-series order for “Demimonde” back in February. J.J. Abrams is set to pen the script, making this the first TV series the producer has written since 2008’s “Fringe.”

In classic Abrams’ fashion, HBO’s official logline for the series is purposely vague: an epic and intimate sci-fi fantasy drama.

Doran will executive produce, along with Abrams and Ben Stephenson — head of television for Abrams’ Bad Robot Productions — in association with Warner Bros. Television.

Bash is the creator of the new UK Channel 4 series “Jerusalem,” which is currently shooting in the UK. Her other small screenwriting and producing credits include Hulu’s “The Looming Tower,” “Masters of Sex,” “Boardwalk Empire,” and “Smash.”
