As we previously reported, Rowan Blanchard will play Halm’s onscreen sis and the prospective series’ title character, Riley.

The Boy Meets World spin-off — which picks up more than a decade after ABC’s TGIF staple went off the air — secured leads Ben Savage and Danielle Fishel in November. In a Tumblr post written soon after she signed onto the pilot, Fishel assured Boy‘s loyal (and — judging by social media — super-jazzed) fans that the new sitcom would share “familiar faces, familiar themes and familiar messages” with the original.

It also shares a key behind-the-scenes player: Boy Meets World creator and executive producer Michael Jacobs is in charge of the pilot, which begins production later this month for consideration on Disney Channel’s 2013-14 schedule. Sitcom vet John Whitesell (Roseanne, Cosby Show) is set to direct.
