The Big Bang Theory franchise is now getting another spinoff of the original series, and people are naturally eager to know if the old main cast members will be reprising their roles. The untitled Big Bang Theory spinoff is expected to focus on Stuart (Kevin Sussman), with his girlfriend Denise (Lauren Lapkus) and Caltech scientist Bert (Brian Posehn) also returning. While these three may be the main characters, there is still potential for others to join the regular cast, as well as a wider range of Big Bang Theory characters who could return in Stuart’s spinoff.
