Anticipation is building for HBO Max’s Big Bang Theory spinoff, Stuart Saves the Universe, which finally began filming in September after a long development period. While the core cast is set, fans have been eagerly speculating about whether original stars—especially Kaley Cuoco—might return.
During a recent Entertainment Tonight interview promoting her new thriller Vanished, Cuoco was asked about reprising Penny—and her reaction said more than her words. Flashing an unmistakable wide-eyed expression, the actress deflected with humor, insisting, “Big eyes! I don’t know what that tells you.” For many fans, it told them everything.
Cuoco has repeatedly expressed her love for Penny, calling the role life-changing both professionally and personally. While nothing is officially confirmed, her playful response has only fueled theories that Penny may pop up—possibly in a very Stuart-style way—when the spinoff premieres in 2026.
