NBCUniversal definitely hasn’t been hesitant about revisiting past hits with former stars, having produced timely revivals for Saved by the Bell and Soleil Moon Frye’s Punky Brewster in the past year or two, and work is currently ongoing for that Battlestar Galactica revival, the Fresh Prince of Bel-Air dramatic reboot, and another Law & Order spinoff.
It’s perhaps unexpected that Mayim Bialik would be met with anything but open-armed acceptance at this point in her career, and for an already established sitcom, no less.
The studio clearly has few qualms with sticking to familiar material.
