As EW previously reported, Zoe Perry is attached to play Sheldon’s mother, who is portrayed on the flagship series by Perry’s real-life mom Laurie Metcalf. Lance Barber, Raegan Revord, and Montana Jordan will also star.

Parsons — who is set to executive produce the comedy alongside creators Chuck Lorre and Steven Molaro, as well as Todd Spiewak — will also narrate the comedy as Adult Sheldon. Jon Favreau will direct and executive produce the series premiere.

The spin-off comes as The Big Bang Theory, currently in its 10th season, is the No. 1 comedy in primetime, with CBS eyeing a two-season renewal should contract negotiations with the cast close.

The Big Bang Theory airs Thursdays at 8 p.m. ET on CBS.
