Deadline reports that the forthcoming Big Bang Theory spinoff Stuart Fails To Save the Universe only came together after its creators found a way to move beyond a conventional sitcom format. The article argues that this matters because the project depends on blending the original show’s world with a more action-adventure and genre-driven style, which led co-creator Chuck Lorre to bring in writer Zak Penn despite Penn having no television comedy background. A further turning point came when fellow Big Bang co-creator Bill Prady joined the process and, according to Lorre, helped unlock the idea after a long period of stalled development.

The article says the project was first announced by HBO Max in early 2023 and that Lorre and Penn spent two years discussing it during the Covid period without making major progress. Penn’s connection to the Syfy series Alphas proved important: Lorre said he admired that show, while Penn said he felt encouraged by an earlier Alphas reference on The Big Bang Theory, specifically in Season 6, Episode 21, where Sheldon reacts to its cancellation. The piece also notes another Alphas link in the casting, with Ryan Cartwright, who starred in Alphas and previously guested on Big Bang, appearing in the new series as one of only a small number of major new characters.
