New 'Big Bang Theory' spinoff in development

The "Big Bang Theory" universe is growing!

Series creator Chuck Lorre is developing a new comedy set in the "Big Bang Theory" universe, which is set to hit Max, the newly combined HBO Max-Discovery+ streaming service.

Lorre would serve as an executive producer. Further details are being kept under wraps -- including any possible involvement from the original cast members, either in front of or behind the camera.

The new project would be the second "Big Bang Theory" spinoff, following "Young Sheldon," currently in its sixth season. It stars Iain Armitage as Sheldon Cooper, a socially impaired child genius introduced as an adult played by Jim Parsons in the original series.

"The Big Bang Theory" ran for 12 seasons on CBS from 2007-2019 and won 12 Emmys. It is also the longest-running multicamera comedy in TV history.
